The volume of a rectangular prism can be found using the formula:

$V = \text{Length} \times \text{Width} \times \text{Height}$

Given:

• Length = 13.2 inches
• Width = 13.8 inches
• Height = 15.9 inches

Now, let's calculate the volume:

$V = 13.2 \times 13.8 \times 15.9$

First, multiply 13.2 and 13.8:

$13.2 \times 13.8 = 182.16$

Next, multiply that result by 15.9:

$182.16 \times 15.9 = 2890.944$

Rounding to the nearest tenth:

$V \approx 2890.9 \text{ cubic inches}$

Thus, the volume of the rectangular prism is approximately 2890.9 cubic inches.
