320 and 448

Step-by-step explanation:

Rectangles van be found using the formula Bh, or base area times height. The base of the unsolved rectangular prism can be found by multiplying 4 by 5 to get 20, this must be multiplied by the height, which can be found by subtracting 4 from 20, which gives you 16. 16 times 20 is 320, which is the volume of the rectangular prism. The two volumes can be added to find the value of the whole figure. 320+128=448, which is the answer to the second box.

x= 3^y
