Question

the surface area of a cube is 384cm^2. find its volume?​

Answer 1

Hey mate ,

Surface area of cube = TSA = 6a^2

384 = 6 a^2

a^2 = 64

a = √64

a = 8 cm [ taking only positive value]

Volume of cube = a^3

= 8^3

= 512 cm^3

Answer 2

Using the formulas:-

A=6a2

A=6a2V=a3

Solving forV

V=6A3/2

V=6A3/236=6·3843/2

V=6A3/236=6·3843/236≈512cm³

So, 512cm³ is your answer.
