Answer:
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.
