Answer:
416 ft
Step-by-step explanation:
We will start with the easiest shape.
10 x 4 x 4 = 160
We will put that to the side and continue.
we see that 20 feet is the whole height of the object but since there is the height of 4 feet on the bottom shape, we will take 4 from 20 to give us 16 feet for the top shape.
16 x 4 x 4 = 256
Now, we add the totals.
256 + 160 = 416
