Question

the dimension of a brick are 24 cm*12 cm*8 cm how many such bricks will be required to build a wall of 20m length 48cm breadth and 6m height?

Answer 1

hope this answer will help you.

Answer 2

L=20 m

B=48/100m

H=6m

l=24/100m

b=12/100m

h=8/100m

let no.of bricks be n

n×volume of one brick= volume of wall

n(24/100×12/100×8/100)= 20×48/100×6

n(1/25000)=1

n=25000
