#### Solution: Leave us a comment of example and its solution (i.e. if it is still somewhat unclear...): Math student
What do all those symbols mean? Is there a more simple format...that you could put this in? Petr
S - surface area of cube
V - volume of cube(s)
r - radius of sphere #### To solve this example are needed these knowledge from mathematics:

Tip: Our volume units converter will help you with converion of volume units. Pythagorean theorem is the base for the right triangle calculator.
