Answer:

New surface area is 384 cm².

Step-by-step explanation:

Given:-

Surface area of a cube is 96 cm².

To find:-

New surface are of cube if edge is doubled.

Solution:-

We know,

Surface area of cube = 6 a²

Where, a is edge of cube

Put the values:

\implies⟹ 96 = 6 a²

\implies⟹ 96/6 = a²

\implies⟹ 16 = a²

\implies⟹ √16 = a

\implies⟹ a = 4

Edge of cube is 4 cm.

Double the edge of cube for finding new surface area.

So,

\implies⟹ 4 × 2

\implies⟹ 8

Edge is 8 cm.

Now,

Put edge in surface area formula:

\implies⟹ 6 × (8)²

\implies⟹ 6 × 64

\implies⟹ 384

Therefore,

Surface area of of cube is 384 cm².
