Solution

## We know volume of cube = side × side × side Volume of the bigger cube = 8 × 8 × 8 = 512 cu. cm Volume of the small cube = 1 × 1 × 1 = 1 cu. cm Number of small cubes used to make the bigger cube = 512 ÷ 1 = 512 We know, Volume of cuboid = length × breadth × height Volume of the cuboid = 16 × 8 × 4 = 512 cu. cm Number of small cubes used to make the cuboid = 512 ÷ 1 = 512 So, we see that same number of small cubes are used to form both the cube and the cuboid.
