Given : A cuboid 20 cm by 10 cm by 4 cm

Constructed using 2 cm  side cubes

To Find :  How many cubes were needed

Solution:

cuboid 20 cm by 10 cm by 4 cm

Cube  2 cm

20/2 = 10

10/2 = 5

4/2  = 2

Number of cubes required = 10 x 5 x 2  = 100

other method

Volume of cuboid  -  20 x 10 x 4  

= 800 cm³

Volume of a cube = 2 x 2 x 2 = 8 cm³

Number of cubes required = 800/8

= 100

100 cubes needed
