Cecilia built a model pyramid out of 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? (1 point)
The volume of a pyramid can be calculated using the formula V = (1/3) * B * h, where B is the area of the base and h is the height.
The area of the rectangular base is given by A = l * w, where l is the length and w is the width.
In this case, l = 8 inches and w = 12 inches, so A = 8 * 12 = 96 square inches.
Using the formula V = (1/3) * B * h, we can calculate the volume of the pyramid.
V = (1/3) * 96 * 20 = 320 cubic inches.
Therefore, the volume of Cecilia's model pyramid is 320 cubic inches.
