A Pyramid is a 3D geometrical figure with a polygonal base where each side of base is joined with triangular faces having a common vertex on the other end.
Here are given two pyramids:

A triangular pyramid is a type of pyramid having a three sided triangular faces whose vertices are joined to a triangular base. It has 4 vertices and 1 base.

A square pyramid is a pyramid four triangular sides joined to a square base. It has 5 vertices and 1 base.

Pyramid Calculator has two calculators. Square Pyramid Calculator is a online tool used to find the area of square base, surface area and volume of square pyramid.Triangular Pyramid Calculator is a online tool used to find the area of triangular base, surface area and volume of triangular prism.

## Pyramid Formula

Step 1 : Read the given problem and observe the quantities given. If side length (s), slant height (l), height (h) are given find the square pyramid parameters. If the Apothem length (a), side length (s), slant height (l) and height (h) are given, find the triangular pyramid parameters.

Step 2 :
Square pyramid parameters can be calculated using the below formulas
• Area of square base = s2
• Surface Area of square pyramid = s2 + 2sl

• Volume of square pyramid = $\frac{1}{3}$ $\times$ b2 $\times$ h
Where s = side length,
l = slant height,
h = height
b = base height

Triangular pyramid parameters can be calculated using the below formulas
• Area of triangular base = $\frac{1}{2}$ $\times$ a $\times$ s

• Surface Area of triangular pyramid = $\frac{1}{2}$ $\times$ a $\times$ s + $\frac{3}{2}$ sl

• Volume of triangular pyramid = $\frac{1}{6}$ $\times$ a $\times$ b $\times$ h
Where a = Apothem length,
s = side length,
l = slant height,
b = base height,
h = height.
Put the values in above formula and get the answer.
