The problem asks us to find the volume of a rectangular prism. The dimensions of the rectangular prism are given as length = 8.1 ft, width = 3 ft, and height = 9 ft.

1. Problem Description

The problem asks us to find the volume of a rectangular prism. The dimensions of the rectangular prism are given as length = 8.1 ft, width = 3 ft, and height = 9 ft.

2. Solution Steps

To find the volume of a rectangular prism, we use the formula:

$Volume = length \times width \times height$

In this problem, length = 8.1 ft, width = 3 ft, and height = 9 ft.

So,

$Volume = 8.1 \times 3 \times 9$

$Volume = 24.3 \times 9$

$Volume = 218.7$

The volume of the rectangular prism is 218.7 cubic feet.

3. Final Answer

218.7 cubic feet
