Question

If the surface area of a cube is 384cm2 . Then its volume is?​

Answer 1

Step-by-step explanation:

Surface area of cube =6l^2

384=6l^2

384/6=l^2

64=l^2

taking square root

l=8 cm

Volume of cube=l^3

Volume of cube=8×8×8

Volume of cube=64×8

Volume of cube=512cm^3

So ,volume of cube=512cm^3

Answer 2

Answer:

Surface area of a cube = 6a²

Surface area of given cube = 384cm²

6a² = 384

a² = 64

a = 8cm

Volume of cube = a³= 8³ = 512 cm³
