Question

If each edge of a cube is doubled,
(i) how many times will its surface area increase?
(ii) how many times will its volume increase?​

Answer 1

Answer:

Step-by-step explanation:

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

T.S.A = 6x2 cm2

TSA=total surface area

Increased length of the edge = 2x

T.S.A = 6(2x)2 cm2 = 24x2 cm2

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