Step 1:
The volume of a square pyramid is calculated by multiplying the square of the base edge with the height of the pyramid and .
The volume of a square pyramid,
Step 2:
From the given diagram, the base edge is the length of the four base edges which is x inches in this pyramid. a = x inches.
The height of the pyramid is from the base to the top, h = inches .
The volume of a square pyramid,
Substituting the known values, we get
So x is 18 inches long.
The side length inches.
The height of the pyramid inches.
