In mathematics, similarity means that two, or indeed more, shapes are identical in terms of angles. While the sides are not identical, they are in ratio to each other e.g. if you multiply one side’s length by two, you must do that to the other sides. One can use it to find out the scale factor of enlargement.

Similar areas are the areas of similar shapes. Their areas can be calculated by finding the square root of the area. This gives the side of a square which has the same area. If this is multiplied by the ratio of the sides of the real shapes in question then you can find the square root of the corresponding square for the other shape. This can be squared to give the area of the other shape.

Similar volumes are the volumes of similar shapes. Their areas can be calculated by finding the cube root of the area. This gives the side of a cube which has the same volume. If this is multiplied by the ratio of the sides of the real shapes in question then you can find the square root of the corresponding cube for the other shape. This can be cubed to give the volume of the other shape.
