To find the volume of a rectangular pyramid, you use the formula V = (1/3) * base area * height.
Given that the base dimensions are 14 inches by 9 inches, the base area is 14 * 9 = 126 square inches. The height is 9 inches.
Plugging these values into the formula:
V = (1/3) * 126 * 9
V = (1/3) * 1134
V = 378 cubic inches
Rounding to the nearest whole number, the rectangular pyramid contains 378 cubic inches.
