to form a cube and find the formula for its surface area experimentally

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 = a*^{2}

Hence, total surface area of cube = Surface area of 6 squares = 6 × *a*^{2} = 6*a*^{2}
