Question

To form a cube and find the formula for its surface area experimentally.​

Answer 1

Let a cube ABCDEFGH is given

Then the net of the cube consist of 6 small squares and could be represented as :

Let the side of the cube is a.

∴ Surface area of 1 square = a × a = a2

Hence, total surface area of cube = Surface area of 6 squares = 6 × a2 = 6a2
