Square Pyramid
You find the base of a figure depending on if it's 2D or 3D 2D- Get a measuring device and find the length of the base. 3D- Easiest way is to split it into parts. For example, you have a pentagon-shaped base, i would split it into 5 and find the base for 1 part and multiply it by 5.
A square based pyramid.

There is 5 faces 4 vertex & 1 base. there is 1 base 4 vertexs & 1 base understand.
1 square yard = 9 square feet.
The 3D shapes that have at least one square face are known as prisms. Prisms are polyhedrons with two parallel and congruent faces called bases, and lateral faces that are parallelograms. When one of the bases of a prism is a square, it is called a square prism. Other examples of prisms with a square face include rectangular prisms and cube-shaped prisms.
