• All Enclosure Volumes are calculated in CuFt (Cubic Feet)
• The dimensions are calculated against a constant: 1728

Example 1: Boxes Standard

Using Fig-1. Multiply the HxWxD (in Inches) and then divide this number against a constant of 1728. Assume values for Fig-1 as: H=12" W=18" D=12". Calculated values become: 12" x 18" x 12" = 2592". Take the value of 2595 and divide it against constant 1728. 2592"/1728 = 1.5 CuFt.

Why 1728?

Well this is because 1-CuFt (Cubic Ft) is really 1-Ft x 1-Ft x 1-Ft (Height (H) x Width (D) x Depth (D). Therefore if 0ne foot = 12" then it stands to reason that 12" x 12" x 12" also equals 1-cubic Ft.

Note: 12" x 12" x 12"=1728" (1-Cubic Ft)

Example 2: Wedges: Simplified Approach

Now lets try calculating an angled enclosure like that shown in Fig-2. The simplest way to do this is to create two (2) rectangular boxes. Square off the top of the box at the angle point. (See Fig-3)

In Fig-3, We calculate the rectangle formed in Box-A portion (Just like we did in the Fig-1 Box example) Record this value. Next add enough size to the box in Fig-3, to be able to make a new complete rectangle as shown in Box-B.

Next calculate Box-B volume (same way as Fig-1 Box).

Divide this Box-B volume by 2, so that we obtain 1/2 of its original value. Add this Box-B 1/2 volume to the Box-A volume, for the ENCLOSURES TOTAL VOLUME.
