Question

(C) A wall of length 12m was to be built across an open ground. The
height of the wall is 4m and thickness of the wall is 24cm. If this
wall is to be built up with bricks whose dimensions are
24cm x 12cm x 8cm, how many bricks would be required?​

Answer 1

Answer:

5000 bricks

Step-by-step explanation:

length of wall = 12m,1200cm

height of wall= 4m,400cm

breath of the wall =24cm

volume of a cuboid = length×breath × height

= 1200×400 ×24

similarly we can find the volume of bricks

= 24×12×8

the number of bricks required to build the wall =(1200×400×24)/(24×12×8)

=5000 bricks
