Answer 2

Answer:

Number of bricks needed = 14400

Step-by-step explanation:

Dimensions of each brick:

l×b×h = 25 cm × 16 cm × 10 cm

Dimensions of the wall:

Length (L) = 24m = 2400

cm,

Breadth (B) = 6m = 600 cm

Height (H) = 0.4 m = 40m

L × B × H = 2400 × 600 × 40

Let number of bricks needed = n

$n = \frac{Volume \: of \:wall}{volume \:of \:a\:brick}$

$=\frac{L\times B\times H}{l\times b \times h }\\=\frac{2400\times 600\times 40}{25\times 16\times 10}$

$=14400$

Therefore,

Number of bricks needed = 14400
