A cube of side length 5 cm is to be polished, what is the total area which needs to be polished?

Open in App

Solution

All the sides of a cube are equal in length. So each side of the cube has a length of 5 cm.
A cube has 6 surfaces, each a square.
Area of single surface = 5 cm x 5 cm = 25 cm2
So, area of all the surfaces = 6 x 25 cm2 = 150 cm2
So, the total area which has to be polished is 150 cm2
