Enter the trash can length (in), the trash can width (in), and the trash can height (in) into the Trash Bag Size Calculator. The calculator will evaluate the Trash Bag Size. 

Trash Bag Size Formula

The following formula is used to calculate the Trash Bag Size. 

TBS = TCL/12 * TCW/12*TCH/12 * 7.481

Variables:

  • TBS is the Trash Bag Size (gallons)
  • TCL is the trash can length (in) 
  • TCW is the trash can width (in) 
  • TCH is the trash can height (in) 

To calculate the trash bag size, divide the length, width, and height, each by 12, multiply those results together, then multiply by 7.481.

How to Calculate Trash Bag Size?

The following steps outline how to calculate the Trash Bag Size.

  1. First, determine the trash can length (in).
  2. Next, determine the trash can width (in). 
  3. Next, determine the trash can height (in). 
  4. Next, gather the formula from above = TBS = TCL/12 * TCW/12*TCH/12 * 7.481.
  5. Finally, calculate the Trash Bag Size.
  6. After inserting the variables and calculating the result, check your answer with the calculator above. 

Example Problem:

Use the following variables as an example problem to test your knowledge.

trash can length (in) = 15

trash can width (in) = 10

trash can height (in) = 30

TBS = TCL/12 * TCW/12*TCH/12 * 7.481 =  ?
