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)

Answer 1

The volume of a pyramid can be found by multiplying the area of the base by the height and then dividing by 3.

The area of the base is length times width, or 8 inches * 12 inches = 96 square inches.

The volume is (96 square inches * 20 inches) / 3 = 1920 cubic inches.

Thus, the volume of Cecilia's model pyramid is 1920 cubic inches. Answer: \boxed{1920}.
