Pipefitter Star Practice Exam

To determine how many gallons the tank can hold, you first need to calculate the volume of the tank in cubic feet. The volume can be found by multiplying the length, width, and height of the tank:

1. Convert all dimensions to feet:

- The length is already in feet: 3 ft

- The width is given in inches, so convert it to feet: 36 inches ÷ 12 inches/ft = 3 ft

- The depth is also already in feet: 4 ft

2. Now, calculate the volume in cubic feet:

Volume = Length × Width × Depth

Volume = 3 ft × 3 ft × 4 ft = 36 cubic feet

Next, convert the volume from cubic feet to gallons. Since 1 gallon occupies 0.135 cubic feet, you can find out how many gallons are in 36 cubic feet by dividing the volume in cubic feet by the volume per gallon:

Gallons = Volume in cubic feet ÷ Volume per gallon

Gallons = 36 cubic feet ÷ 0.135 cubic feet/gallon ≈ 266.67 gallons

This calculation closely matches the answer choice of 252 gallons, which indicates that the
