How to Calculate the number of blocks required Blocks to build fence around a plot of Land.

Follow these steps:

1. Determine the Perimeter of the Plot.
- Formula for Perimeter (P):
- Rectangular/Square Plot: ( P = 2 times (Length + Width).
- Irregular Plot: Measure all sides and sum .
- Subtract Gates/Openings: Deduct the width of any gates from the total perimeter.

2. Decide Fence Height (H)
- Choose the desired height of the fence (e.g., 1.8 meters or 6 feet).

3. Block Dimensions
-Standard Block Sizes (adjust based on local availability):
- Length (L): 0.45 meters (18 inches).
- Height (H_b): 0.23 meters (9 inches).
- Include Mortar ts (if applicable): Add ~10mm (0.01m) to block length/height if mortar is used.

-4. Calculate Blocks per Course (Horizontal Row)
{Blocks per Course} = {Adjusted Perimeter (meters) \ {Block Length (meters)

- Round up to the nearest whole number (partial blocks require cuts).

5. Calculate Number of Courses (Vertical Layers)
{Number of Courses} = {Fence Height (meters) \ {Block Height (meters)

- Round up to ensure full coverage (e.g., 1.8m ÷ 0.23m ≈ 8 courses).

6. Total Blocks Needed
{Total Blocks} = {Blocks per Course} \{Number of Courses}


7. Add Waste Allowance
- Add 5% extra to for breakage, cuts, or errors.

Example Calculation
Plot: 15m × 30m (Perimeter = (2 times (15 + 30) = 90 {m}.
-Gate: Subtract 3m → Adjusted Perimeter = 87m.
-Fence Height: 1.8m.
-Block Size 0.45m (length) × 0.23m (height).
- Blocks per Course 87 {m} ÷ 0.45 {m} ≈ 193{blocks}.
- Number of Courses 1.8{m} ÷ 0.23 {m} ≈ 8{courses} .
-Total Blocks 193 x 8 = 1,544 {blocks}.
-Add 5% Waste: ( 1,544 x 5%) = 77 blocks 1544 +77 = 1621{blocks.

Key Considerations
Mortar ts: Adjust block dimensions if mortar is used.
- Pillars/Posts: Add blocks for structural pillars if included.
- Complex Shapes: For non-rectangular plots, measure each side individually.

Use this formula with your plot’s specific measurements to estimate the required blocks.

It now I know that education does not guarantee conscience and common sense, how would a SAN openly agreed with the EVIL combination that may likely affect his faith if this people eventually become (God forbid) president and vice president come 2023,. Money rules Christians politicians mind in this country.

Banks failure, I don't get it, you can't withdraw more than 150k on ATM, why will Central bank allow POS to withdraw more than what Bank ATM is given daily? That is lapses from both CBN/commercial Banks.

Watch video here :
https://www.youtube.com/watch?v=Nll-MGEqd3Q

A video of Yoruba actress Victoria Ajibola aka Omolocal lamenting bitterly in a bank branch over her missing money has sparked reactions on social media.

The movie star in her statement revealed that the bank has been nonchalant about her predicament and even called security on her Ajibola added that she has never taken more than N150k in a day from her and N1m just disappeared within thirty minutes.

She lamented over the fact that she has never collected such a huge sum at once from her and N1m was wiped in just thirty minutes with reference to a POS machine.

Omolocal added that she doesn't collect beyond N150k daily for herself and because she has been recording in the bank, the police have been called to kick her out.

In another clip, the actress was seen in a video crying bitterly as she spoke to someone on the phone. "The situation of this country is getting worse everyday like see what UBA did to me since last week Friday they withdraw all money through pos and nothing as been done to it since last week Friday and when we got to the POS paycom office of Nigeria @opay.ng they said is only UBA ubagroup that can send them an email before they can do anything to it but still UBA could not do anything to it.

Is 11street some kind of MMM too?

All I can see, is that there's no genuity in your claim, do they removed more that the money you are owing them?? If not your claim is baseless to my understanding.

The DSS report is to justify any killing from now and give excuses that is gorilla fight

You have explained better.

saferoom:
The best practice is to fill the Blocks in the foundation with weak concrete (or normal concrete if you can afford it). The reason for filling blocks with concrete is obvious: To make the blocks stronger as if they are concrete blocks.
There is what is called EARTH PRESSURE acting on the blocks which makes the blockwork act as if they are Retaining Walls. So leaving them Hollow like that is not the best however since to avoid the cost of filling them with concrete, they just assign a labourer to block the holes before putting the chain beam to connect all the columns (pillars)

Then coming to the question of filling the blocks with laterite (filling sand), is not a common practice thought some people do it. It is not advisable to have earth on both sides of the block and also inside the blocks. The soil inside the holes of the blocks doesnt offer added strength like concrete will do, so it becomes an added load on the blocks. It is like a pregnant woman. The baby inside her is an added load. Whatever doesnt make you stronger makes you weaker. It's a universal principle.

If you have added questions you can ask on this thread on Nairaland

He did so to save his family he knew they may rope him if he eventually fight back and kill any of the DSS officers who came to kill him but their failure to get him killed led to the arrest of all the occupants of the house and even killed two EVEN with his action not fighting back they still planted guns and animation in his house. Then note he who run for fight today live to fight tommorow

PrinceOfLagos:

Nonsense

So why did Sunday Igboho cowardly turned to a cat and disappeared at the sight of the military and DSS?

How much.

How much.

Very very real, the only thing is that the figures might be inflated by our government.

Iwillsurvivedis:
Well personally I don't know anyone who has been infected or died of the novel covid-19 virus, with the hype and rate of increase as purported by our government and the secrecy sorrounding those they claim to have it, I have my doubts regarding the figures.

I have personally followed Ghana on worldometer.info and Ghana's covid cases has remained below 1300 and just 9 deaths over the past week(s). So what does Ghana know that we don't.

Also I read a report on yahoo news saying sunlight easily kills the virus and we all know that the sun in Nigeria can boil yam in the right circumstance.

Another thing I noticed is that as soon as the European union gave Nigeria a 27 billion grant, the cases started to rise uncontrollably. Anyway thats my observation.

So do you know anyone with the virus or has the NCDC Being to your area to pick any suspected case.

Let us know.

Deepfeel:
Its a shame a whole Lagos

It is quite unfortunate that Nigeria government continue to fail the masses in their dealings with us.

What is hard in giving palliative to the Masses?? When its time to collect Land Use they know every house Number in Lagos, using the same number to send palliative to Lagosians now has become rocket science. May God help Us.

That's my fear oo I hope all ventilator would not be hijack by this big men in the country coz we have less than 500 pcs. My prayer is may God arrest this virus now, if not the masses will suffer it most, they may end up bribing doctors in millions of naira to get ventilator.

babytoun:
lagos is the new UK for them ...very soon big men go collect all the ventilators

Is the water projects cut across length and breadth of the estate??

Would it be channel to each building??

I think site visitation is required

1, Area of 1acre of land is 4046.9sqm which
Length is 73.85m and breadth is 54.8m.

Assuming your fence height is 2m above Natural Ground level (NGL) and it foundation is 500mm underneath. Therefore Total Height of fence is 2.5m

Total lenght of your fence will be 73.85 + 73.85 + 54.8 + 54.8 = 257.3m

Fence Square meter is 257.3 x 2.5m = 643.25m

Area of block is 0.101sqm

Number of blocks needed
643.25 ÷ 0.101 = 6369pcs then add 5% waste which is 318 so Total blocks required is 6687 approximately 6700 blocks

Average good 6inch block sold For N180
180 x 6700= 1,206,000

Assuming 2gates (Tentatively)

Excavation: budget N180,000.

Foundation Concrete: 13cum @ 45,000/1cum = N585,000 (cement sand granite water and workmanship)

Laying of fence: between 85bags and 100bags of cement at least 60 tonnes of sand water budget 30,000 workmanship budget 450,000

And you're right here falling for Dino's antics! Funny.
Buhari wasn't sold to anyone and no one is chewing fingers, only in imagination. It will do you like film trick in 2019!

By their fruit we shall know them.

Answering this Buhari is justva waste of time, Buhari is the only living former and present President with no investment.
