Find the volume of a rectangular prism (a box) that is

19
19 feet long,
1
1 feet wide and has a height of
9
9 feet.

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

Volume = Length × Width × Height

Plugging in the given dimensions:
Volume = 19 feet × 1 feet × 9 feet

Simplifying the multiplication:
Volume = 171 feet^3

Therefore, the volume of the rectangular prism is 171 cubic feet.
