A "Caution Wet Floor” warning sign is in the shape of a rectangular pyramid. It is 31 in. tall and has a base whose dimensions are 12 in. by 20 in. What is the volume of the sign?(1 point)
The volume of a rectangular pyramid is given by the formula V = (1/3) * base area * height.
First, we need to determine the area of the base of the rectangular pyramid:
Base area = length * width
Base area = 12 in. * 20 in.
Base area = 240 in²
Now, we can calculate the volume of the rectangular pyramid:
V = (1/3) * 240 in² * 31 in.
V = (1/3) * 7440 in³
V = 2480 in³
Therefore, the volume of the "Caution Wet Floor" warning sign is 2480 cubic inches.
