find the volume of a square pyramid with a base length of 9 cm and a height of 4 cm

Answer 1

The formula for the volume of a square pyramid is:

V = (1/3) x base area x height

Since the base is a square with a length of 9 cm, the area of the base is:

base area = length x width
base area = 9 cm x 9 cm
base area = 81 cm^2

Now we can plug in the values into the formula:

V = (1/3) x 81 cm^2 x 4 cm
V = (1/3) x 324 cm^3
V = 108 cm^3

Therefore, the volume of the square pyramid is 108 cubic centimeters.
