I am building an L-shaped wall 3 ft x 8ft length x 3ft height. How many 4in concrete blocks willI need?

Question

Single skin!!!

A British Standard 4 inch block is 4"depth x 8" hight x 16" length.

Answer 1

work it out in square metres you get ten block to a square metre you will need about 40 block im a bricklayer so trust me i know hope this helps

Answer 2

assuming;
ur using 4 x 8 x 16 block

take the length and convert to inches and divide by 16
take the height and convert to inches ad divide by 4
take the 2 sums and x them together.....

11 ft = 132 divide by 16 ( length of block) = 9 ( rounded off)
3 ft= 36 divide by 4 ( height of block) = 9

9x9= 81

i'd get 85 just in case u break a few....

Answer 3

It depends where your house is and where you want to place the extensions. These rules are for the UK If your lobby, or porch has a footprint area of less than 3 square metres measured outside the porch and 3 feet x 8 feet is 2.43 square metres, and if it is more than 2 metres from your property boundary and the road, you don't need planning permission. For a conservatory, it depends what type of house you have. If you have a terraced house, the size of conservatory you can erect without planning permission must be no more than 10% of the volume of your house or 50 cubic metres. If you live in a semi or detached house, the limit is 15% of the volume of your house or 70 cubic metres.

Answer 4

Are the concrete blocks 4 inches high or 4 inches wide or 4 inches long?

Answer 5

You can do it by comparing volume, but you need to convert the feet to inches first. The wall is 36x96x36 so it's 124,416 cubic inches of brick you need.

You did not mention the width or depth of the bricks so I'll assume it's a cube (but I bet it really isn't). 4x4x4 is 64 cubic inches, so divide 124,416 by 64 and the absolute minimum number of bricks is 1,944.

Depending on the actual dimensions of the brick you may need more or less since you are not building a cube shaped wall.

Answer 6

I think 72 I did 3 * 8 * 12 / 4

Answer 7

length times width= area
8ft= 96 " times 3ft= 36" times 3ft= 36"
96" times 36" = 3456" = 864 4" concrete blocks
36" times 36" = 1296" = 324 4" concrete blocks
864+324 = 1,188 4" concrete blocks

Answer 8

It's impossible to answer with certainty unless you give us all the dimensions of the block to be used.
Is 4" the height or width? Length of block?

Answer 9

Divide total SF by 127

Answer 10

call the brickyard or a bricklayer and give them the info. They can tell you to the brick.
