Question

How many 20 cm cubes can be placed in cuboidal box of length 4m, breadth 3m and height 2 cm?

Answer 1

Volume of cube = side×side×side
= 20×20×20
= 800cm^3.

Volume of cuboid = l×b×h
= 4m×3m×2cm
= 400cm×300cm×2cm
= 240000cm^3.

Number of cubes = Volume of cuboid/Volume of cube
= 240000/800
= 300.

So,300 cubes can be placed in it.
