Question

A wall is made using cubes of side 4 meters. length, breadth and thickness of the wall are 20m, 16m and 12m respectively. how many cubes are needed to build the wall?

Answer 1

Solution :-

Each edge of the cube = 4 m

Volume of each cube = Edge*Edge*Edge

⇒ 4*4*4

= 64 m³

Length of the wall = 20 m
Breadth of the wall = 16 m
Height of the wall = 12 m

Volume of the wall = Length*Breadth*Height

⇒ 20*16*12

⇒ 3840 m³

Number of cubes needed to build the wall = Volume of the wall/Volume of each cube

⇒ 3840/64

⇒ 60 cubes

Answer.
