Question

A wall of dimensions 20m by 15m by 10m is made up of bricks,each measuring 10m by 4 cm by 3 cm.Find the number of bricks required.

Answer 1

Answer:

Step-by-step explanation:

Length of wall =20

B of wall=15

H of wall=10

Volume of wall=l*b*h

=20*15*10=3000

Length of brick=10

B of brick=3

H of brick=4

Vol of Brick=10*3*4=120

Let n be the no of bricks

n* vol of Brick=vol of wall

n*120=3000

n=3000/120

n=25

So the no of bricks is 25
