What is a Rectangular Pyramid?

A pyramid with a rectangular base.

A rectangular pyramid is a three-dimensional geometric shape that has a rectangular base and four triangular faces that converge at a single point called the apex.

How to Calculate the Volume

Calculating the volume requires the base dimensions and the height.

1
Measure the length and width of the rectangular base.
2
Measure the vertical height from the base to the apex.
3
Multiply length, width, and height, then divide by 3.

Rectangular Pyramid Volume Formula

The standard equation for a rectangular pyramid.

V = \frac{1}{3} l w h
V Volume
l Base Length
w Base Width
h Pyramid Height

Where 'l' is base length, 'w' is base width, and 'h' is the vertical height of the pyramid.

Frequently Asked Questions

Is the height the same as the slant height?

No. The vertical height (altitude) is the straight line from the center of the base to the apex. Slant height is measured along the face of the pyramid.

Why do we divide by 3?

Geometrically, the volume of any pyramid is exactly one×third the volume of a prism with the same base area and height.

Can this be used for a square pyramid?

Yes, a square pyramid is just a special case of a rectangular pyramid where length equals width.

What if I only know the slant height?

You will need to use the Pythagorean theorem to calculate the vertical height before you can use the volume formula.
