Surface area of cube = 6 (side)²
∴ 96 = 6*(side)²
∴ side = √(96/6) = √16 = 4cm
We now have side of cube.
Therefore, volume = (side)³ = 4*4*4 = 64 cubic cm.
∴ 96 = 6*(side)²
∴ side = √(96/6) = √16 = 4cm
We now have side of cube.
Therefore, volume = (side)³ = 4*4*4 = 64 cubic cm.

ok, so firstly we must find the length(l),
we have got the area which is 96 cm².
Now,
6l²=96
so, l=√16=4 cm.
Now, as you know, the volume of cube is l³
so, l³=(4)³
=64 cm³
that's simple. Hope it helped. ^_^

QwertyZoom:
I was so sure someone was gonna confuse a square's surface area with a cube's.
sorry for the mistake
Nah, it's a common mistake, no need to say sorry ;)
oh, ok. ^_^
