Question

How many bricks will be required for a wall 8m long 6m high and 22.5cm thick,if each bricks measures 25 cm ×11.25cm ×6cm?

Answer 1

Step-by-step explanation:

wall:::

length =8m=800cm

breadth=22.5m=2250cm

height=6m=600cm

$volume \: of \: wall = (800 \times 600 \times 22.5) {cm}^{3}$

brick :::

length=25cm

breadth=11.25cm

height=6cm

$volume \: of \: brick = (25 \times 11.25 \times 6) {cm}^{3}$

$bricks \: required = \frac{800 \times 600 \times 22.5}{25 \times 11.25 \times 6}$

$\frac{10800000}{1687.5}$

$= > 6400$

= > 6400 \: bricks \: are \: required
