Imagine a wall that is made using cubes of the given dimension. We can easily figure out the number of cubes needed by using the simple unitary method.
Volume of a single cube = side³ = 4³ m³
Volume of the cuboid= length x breadth x height = 20 x 16 x 12 m³
Now, for covering 4³ m³ volume, you would need= 1 cube
(since that's the volume of a single cube!)
And for covering the entire 20 x 16 x 12 m³ volume of the wall, you would need =
(20 x 16 x 12)÷(4³) number of cubes!
