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