Question

find the volume of a cube whose total surface area is 384 surface metre square​

Answer 1

Answer:

T.S.A of cube = 6a² = 384m²

a² = 64

a = 8

edge of cube = 8m

Volume of cube = a³ = 8 x 8 x 8

= 512

Answer 2

Step-by-step explanation:

Answer

Let a be the side of the cube. Given that T.S.A = 384 sq. cm.

i.e., 6a

=

6

384

=64

∴a=

64

=8cm

Hence, Volume =a
