The surface area of a cube is 216 sq. cm. what is it’s volume

First we need to find it’s length/width which we can do by dividing 216 by the amount of faces it has and then divide that result by 2

216/6=36
36/2=18

And volume is pretty much just 3 times that answer

3(18)=54

The volume is 54 cm^3

It’s 24.6 after you round to the nearest tenths the answer should be 25.0
