Question

if each edge of cube is doubled what will be the changes in its surface area​

Answer 1

Answer:

Yes, and by 4 times

Step-by-step explanation:

If each edge of the cube is doubled, then it becomes 2 l.

New surface area = 6 (2 l) 2 = 24 l2 = 4 × 6 l2

Clearly, the surface area will be increased by 4 times.
