Given :
Side of cube=s=4m
length of wall=20m
breadth of wall=16m
Thickness of wall=12m
To find : how many cubes are needed to build the wall
Solution:
Before we find the number of cubes required to build the wall.Let us find out the volume of cube
Volume of cube=S³=64m³
Volume of wall=lengthx breadthx thickness=20x15x12 m³
Total number of cubes =Volume of wall/volume of cube
= 20x16x12/64
=3840/64
=60
∴Number of cubes required to build wall is 60.
