Question

Awall was to be built across the open ground to cover a width of 10m. The height
29.
of the wall is 6m and thickness of the wall is 24cm. If this wall is to be built with
- bricks whose dimension are 24cm x 12cm X 8cm. How many bricks would be
required?​

Answer 1

Step-by-step explanation:

Length of the wall = 10 cm = 1000 cm

Height of the wall = 4 m = 400 cm

Thickness of the wall = 24 cm

Volume of the wall = 1000 * 400 * 24 cm3

Volume of each brick = 24 * 12 * 8 cm3

No. of bricks required =

$\frac{volume \: of \: the \: wall}{volume \: of \: each \: brick}$

$= \frac{1000 \times 400 \times 24}{24 \times 12 \times 8} \\ = 4166.667$

Since, the brick is to be taken as a whole, so to build the wall 4167 bricks are required.

I hope this may help you

Answer 2

Step-by-step explanation:

Length of wall = 10m

Height of wall =  4m 

Thickness of wall = 24cm or 0.24m 

Volume of wall = Length×breadth×height

                        = 10×4×0.24 = 9.6 m³

Dimensions of brick = 24cm×12cm×8cm or 0.24m×0.12m×0.08m

 Volume of brick = 0.24m×0.12m×0.08m

= 0.002304 m³

Therefore Number of bricks required = Volume of wall ÷ Volume of 1 brick   =  9.6 m³ ÷ 0.002304 m³

                               = 4166.66 (approx)

Therefore,Number of bricks required to make the wall

= 4166(approximately)
