find the volume of a square pyramid with a base length of 9 cm and a height of 4 cm
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.
To find the volume of a square pyramid, you can use the formula:
Volume = (1/3) × base area × height
First, let's calculate the base area of the square pyramid:
Base area = (base length) × (base length)
= 9 cm × 9 cm
= 81 cm²
Now, substitute the values into the volume formula:
Volume = (1/3) × 81 cm² × 4 cm
= (1/3) × 324 cm³
= 108 cm³
Therefore, the volume of the square pyramid is 108 cm³.
