Answer:

60 feet cubed

Step-by-step explanation:

We are told type of pyramid is a rectangular pyramid.

The volume of a rectangular pyramid = 1/3 × Length × Width × Height

We are told that the pyramids have a base of 4 feet by 5 feet and a height of 4.5 feet.

Volume for one of the pyramid =

1/3 × 4 × 5 × 4.5

= 30 cubic feet

Since the pyramid has the same measurements, that means the second pyramid also has the volume of = 30 cubic feet.

The total volume of the figure of the two pyramids stacked together = 30 cubic feet + 30 cubic feet = 60 cubic feet or 60 feet cubed.
