To calculate the volume of the rectangular tank with the given dimensions, we can use the formula for the volume of a rectangular prism:

$V = \text{length} \times \text{width} \times \text{height}$

From the image, the dimensions are:

• Length: 20 inches
• Width: 32 inches
• Height: 1 ¼ inches, which is equivalent to 1.25 inches.

First, we calculate the volume in cubic inches:

$V = 20 \times 32 \times 1.25 = 800 \, \text{in}^3$

Next, we convert cubic inches to cubic feet. There are 12 inches in a foot, so:

$1 \, \text{cubic foot} = 12 \times 12 \times 12 = 1728 \, \text{cubic inches}$

Thus, we divide the volume in cubic inches by 1728 to convert to cubic feet:

$V = \frac{800}{1728} \approx 0.463 \, \text{ft}^3$

The correct answer is not listed as an option, but it should be close to this calculated value. If rounding adjustments or other measurement interpretations are considered, we might expect a recheck on the options or input interpretation.
