Question

If the total surface area of a cube is 384 mm, find its volume.​

Answer 1

Answer:

V≈512

Step-by-step explanation:

Using the formulas

A=6a2

V=a3

Answer 2

Answer:

Step-by-step explanation:

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

i.e., 6a  ^2  = 384⇒a^ 2  =   384/6  = 64.

∴a =  square of 64   = 8 cm.

Hence, Volume =a^3 = 8 ^3  = 512 cm ^3.
