Question

If the edge of a cube is doubled them how many time it's total surface area will become as compared to it's original surface area

Answer 1

Let the length of the edge of the cube be 'x' cm

Total surface area = 6x2 cm2

Increased length of the edge = 2x

Total surface area = 6(2x)2 cm2 = 24x2 cm2

If the edge of the cube is doubled surface area of the cube increases by 4 times.
