v = 8x

v = 512x

FORMULA FOR SURFACE AREA OF CUBE

a = Edge of cube

Surface area of cube = 6 * a

Volume of first cube (V) = 8

a

a = 2

Edege of first cube is (a)= 2 unit

Volume of second cube (V) = 512

A

A = 8

Edege of second cube is (A)= 8 unit

Edege of first cube is (a) / Edege of second cube is (A) = 2 Unit / 8 Unit = 2 / 8

Surface area of first cube (6*a

= 4 / 64

=1 / 16
