Celissia built a model pyramid at a foam. Her model is 20 inches high with a rectangular base that is 8 inches long and 12 inches wide. What is the volume of her model in cubic inches??
The volume of a pyramid can be calculated using the formula:
Volume = (1/3) * Base Area * Height
The base of the pyramid is rectangular, so the base area is length * width:
Base Area = 8 inches * 12 inches = 96 square inches
Plugging in the values into the formula:
Volume = (1/3) * 96 square inches * 20 inches = 640 cubic inches
The volume of Celissia's model pyramid is 640 cubic inches.
