A cube is a 3-dimensional object that has equal dimensions in all three directions. That is, a cube has the same length, width and height. One can consider a cube to a square in 3-dimensions. Thus, all the faces of a cube are squares.
If a cube has a side length (= length = width = height) of 1 m, we can calculate its volume by using the following equation:
volume = (side length)^3
= (1 m)^3 = 1 m^3
Thus, a cube with a side length of 1 m has a volume of 1 m^3.
1 m^3 is also equal to 100 liters. Thus, a cube that has a side length of 1 m has a volume of 1 m^3 or 1,000 liters. In other words, it can contain 1,000 liters of water, or any other substance.
Hope this helps.
