The image above represents a square pyramid. To calculate the volume of a square pyramid requires two essential parameters which are the base edge and height of the square pyramid.
The formula for computing the volume of a square pyramid is:
V = ha² / 3
Where:
V = Volume of the Square Pyramid
a = Base edge of the Square Pyramid
h = Height of the Square Pyramid
Let’s solve an example
Find the volume of a square pyramid with a base edge of 6 cm and a height of 11 cm.
This implies that:
a = base edge of the square pyramid = 6
h= = height of the square pyramid = 11
V = ha² / 3
V = 11(6)² / 3
So, V = 11(36) / 3
V = 396 / 3
V = 132
Therefore, the volume of the square pyramid is 132 cm3.
Calculating the Base edge of a square pyramid when Volume and Height are Given
The formula is a = √(3V / h)
Where;
V = Volume of the Square Pyramid
a = Base edge of the Square Pyramid
h = Height of the Square Pyramid
Let’s solve an example:
Find the base edge of a square pyramid with a volume of 50 cm3Â and a height of 20 cm.
This implies that;
V = Volume of the square pyramid = 50 cm3
h = height of the square pyramid = 20 cm
a = √(3V / h)
a = √(3(50) / 20)
That is, a = √(150 / 20)
a = √7.5
a = 2.739
Therefore, the base edge of the square pyramid is 2.739 cm.

Calculating the height of a square pyramid when Volume and Base edge are Given
The formula is h = 3V / a2
Where;
a = Base edge of the square pyramid
V = Volume of the Square Pyramid
h = Height of the Square Pyramid
Let’s solve an example:
Find the height of a square pyramid with a volume of 250 cm3 and a base edge of 7 cm2
This implies that;
V = Volume of the square pyramid = 250 cm3
a = Base edge of the square pyramid = 7 cm
h = 3V / a²
h = 3(250) / 7²
Then, h = 750Â /Â 49
h = 15.306
Therefore, the height of the square pyramid is 15.306 cm.
