Calculating Enclosures
It is recommended to build your enclosure from at least 3/4" thick MDF (medium density fiberboard). Make sure the enclosure is sealed airtight.
Calculating External Volume
To calculate box volume, measure the outside Width x Height x Depth of the enclosure. Example: 12" x 14" x 9" = 1512 cubic inches.
Next, you must convert cubic inches into cubic feet. To do this, you must divide the cubic inches total by 1728". Example: 1512 / 1728 = 0.875 cubic feet.
Calculating Internal Volume
To calculate the internal (net) volume of the above box, you must first multiply the thickness of the wood you are using by Two (2). Example: 3/4" x 2 = 1.5 inches.
Next, subtract 1.5 inches from each of the outside measurements of the box:
- Width: 12" - 1.5" = 10.5"
- Height: 14" - 1.5" = 12.5"
- Depth: 9" - 1.5" = 7.5"
Multiply the new totals (Width x Height x Depth). Example: 10.5" x 12.5" x 7.5" = 984.375 cubic inches.
Next, you must convert cubic inches into cubic feet. To do this, you must divide the cubic inch total by 1728". Example: 984.375 / 1728 = 0.5696 cubic feet.
