How do you calculate the volume in gallons of a tank that is 75 feet long, 20 feet wide, and 10 feet deep?

To find the volume of a tank measured in feet and convert that volume to gallons, the correct approach is to multiply the length, width, and depth of the tank to get the volume in cubic feet first.

In this case, the tank has dimensions of 75 feet in length, 20 feet in width, and 10 feet in depth. The volume in cubic feet can be calculated by using the formula for the volume of a rectangular prism:

Volume = Length × Width × Depth

Volume = 75 ft × 20 ft × 10 ft = 15,000 cubic feet.

Once you have calculated the volume in cubic feet, the next step is to convert cubic feet to gallons. There are 7.48 gallons in one cubic foot, so you would multiply the volume in cubic feet by this conversion factor to determine the volume in gallons:

Volume in gallons = Volume in cubic feet × 7.48 gallons/cubic foot.

This method is precise and essential for determining the tank's capacity when working with water systems. Other approaches, such as using only depth and width or squaring dimensions, would not yield an accurate volume for a three-dimensional object like a tank. Additionally, summing dimensions does not provide any meaningful
