How to find the volume of a cube
Recall that a cube has all edges the same length. Also called sides or facets. A cube has 6 faces which are all squares, so each cuve face has 4 equal sides and all 4 interior angles are right angles.
If you want to find volume of a cube you have to multiply the lenght of any egde of itself two times. So if we have a cube which edge is 5, the cube volume is 5 x 5 x 5 = 125.
Imagine that a cube is like an empty box and has nothing inside him. The sides of the box have 0 thickness. If so then the cube has 0 volume. When we speak about the box volume, we are really talking about how many units of cube would fit inside it or how much water it can hold.
Many textbooks simply say "the volume of a cube" to mean the same thing. But strictly correct way of saying it is "the volume enclosed by a cube"- how much space there is inside box. On the other hand, this isn't throughout correct in the mathematical sense. What they often mean when they say this is the volume enclosed by the cube.
Think of it this way: You can take a real metal box, melt it down and you would end up with a small drop of metal. If the metal box was made of metal with 0 thickness, you would get no metal at all. So then box side thickness is 0 we say that cube has no volume.
Surface Area The surface area of a cube is 6s^2, where s is the length of one edge.
Properties of a cube Volume The volume is s^3 where s is the length of one edge.
