Question

How many bricks will be required to construct a wall which is 8m long, óm high

and 22 cm thick, if each brick measures 25cm x 11em x 6cm.​

Answer 1

Answer:

GIVEN, (FOR THE BRICKS)

L= 25cm

B= 11cm

H = 6 cm

So, volume = lxbxh = 11 x 6 x 25 = 1650 cm³

Now,

Given, (FOR THE WALL)

L= 8 m = 800 cm

H = 6m = 600cm

B = 22 cm

So, the volume = lxbxh = 800 x 600 x 22

=10,560,000 cm³

So, the number of bricks = 10,560,000 /1650

=> 6400
