Question

how many bricks are required to build a wall of height 2.88 m and width50cm if the length of each brick is 12cm and breadth is10 cm ?​

Answer 1

Step-by-step explanation:

Given:

• Height of wall= 2.88m= 288 cm
• Breadth of wall= 50 cm
• Length of 1 brick= 12 cm
• Breadth of 1 brick= 10cm

Area of wall=l×b=(288×50) cm²

Area of 1 brick=l×b=(12×10) cm²

.°. No.of brick needed

$\frac{area \: of \: wall}{area \: of \: 1 \: brick}$

$= \frac{288 \times 50 \: cm {}^{2} }{12 \times 10 \: cm {}^{2} } = 120$

Thus, 120 bricks required to build the wall.
