Question

Find the number of bricks of size 20cm×12cm×5cm required to build a wall whose volume is 60m3.​

Answer 1

Number of bricks is 5

Explanation:

We have volume of wall 60m^3. Then we are also given number of bricks size 20cm ×12cm× 5cm.

By multiplying this number we grt 1200cm^3. But answer is needed in meter so divide 1200 with 100 because to change cm into m we need to divide with hundred. Then we have 12m^3 as volume of bricks.

To get no. of bricks we have formula

N = volume of wall ÷ volume of bricks

N = 60 ÷ 12

N = 5

Thus the number of bricks is 5.
