13. 27

14. 168

15. 189

13) 27 units³

14) 160 units³

15) 189 units³

Step-by-step explanation:

To find the volume of a rectangular prism, we need to multiply the length, width, and height of the figure together.

The dimensions of figure 13 are 9, 3, and 1

9 · 3 · 1 = 27

The volume of the figure is 27 units³.

The dimensions of figure 14 are 5, 8, and 4

5 · 8 · 4 = 160

The volume of the figure is 160 units³.

The dimensions of figure 15 are 3, 9, and 7

3 · 9 · 7 = 189

The volume of the figure is 189 units³.

I hope this helps ^^ Good luck :]
