The following figure is a right pyramid with an isosceles triangle base. Find the volume of the pyramid if the height is 20 cm. Solution: First, we have to calculate the area of the base. To do that, we would need to get the height of the isosceles triangle that forms the base. Usi...
A pyramid has a base and triangular sides which rise to meet at the same point. The base may be any polygon such as a square, rectangle, triangle, etc. The general formula for the volume of a pyramid is: Area of the base * Height * 1/3 The volume of a pyramid with a rectangular...
There are different types of pyramids since the base of the pyramid can be a rectangle, a triangle, a square, or even a pentagon. All you need to do is to compute the area of the base of the pyramid accordingly and then multiply by the height. In this lesson, you will learn how to...

If you're given the slant height of the pyramid, it represents the hypotenuse of a right triangle formed by itself, the height of the pyramid, and 1/2 the length of the pyramid's base. Use the Pythagorean theorem: a2+b2=c2 to find the height of the pyramid. In this casecis the sl...
Octagonal pyramid Tetrahedron volume calculation As an example, let's take the example of a loose-leaf tea pyramid: Choose the shape of the base. In our case, it's a regular triangle. Type the pyramid's height. Assume that for a tea pyramid, it's equal to 1.2 in. Enter the side le...
where Abis the area of the base and h is the height. If the pyramid has a triangular base, visualize tipping the base on one end. It's a triangle with base b and height l. You calculate the area using the formula (1/2) × b × l,...
triangular lateral surfaces and a three or four sided surface, respectively, at its base. When we calculate the surface area of the pyramid below we take the sum of the areas of the 4 triangles area and the base square. The height of a triangle within a pyramid is called the sla...
A frustum of a pyramid has the two polygonal bases such as square, triangle etc. The lateral surfaces of a frustum of a pyramid are in trapezium shape. The axis of a frustum is almost always the pyramid’s axis (the original shape). A frustum is a right frustum if the axis is ...
