What is the volume in cubic feet of a rectangular-shaped fuel tank measuring 60 inches in length, 30 inches in width, and 12 inches in depth?

To find the volume of a rectangular-shaped tank, you need to use the formula for volume, which is length multiplied by width multiplied by depth. However, it is essential that all dimensions are in the same unit before carrying out the calculation.

In this scenario, the tank measurements are given in inches, and since the options provided for the answer are in cubic feet, you will first convert the dimensions from inches to feet. To do this, you need to divide each measurement by 12 (since there are 12 inches in a foot).

Here's the conversion:

• Length: 60 inches ÷ 12 = 5 feet

• Width: 30 inches ÷ 12 = 2.5 feet

• Depth: 12 inches ÷ 12 = 1 foot

Now that we have all dimensions in feet, you can calculate the volume:

Volume = Length × Width × Depth

Volume = 5 feet × 2.5 feet × 1 foot = 12.5 cubic feet.

This calculation shows that the correct volume of the fuel tank is indeed 12.5 cubic feet, which corresponds to the option that was identified as the answer. Understanding the process of unit conversion and applying the volume formula correctly
