Building and calculating a wedged enclosure is a little more difficult
then the previous type of enclosures. Calculating a wedged enclosure
volume is a 7 step procedure.
Step One: Measure the Height
Step Two: Measure the Width
Step Three: Measure the Top and Bottom of the enclosures depth
Step Four: Add the depth together
Step Five: Divide the depth by two
Step Six: Height x Width x Results of step five
Step Seven: Divide the results were in step six by 1728
(12 x 12 x 12=1728 which equals to 1.0 cu. ft.)
Complete formula should look like this
Top of Depth + Bottom of Depth=________/ 2=_________
Height x Width x Depth / 1728=_____________________

13.5-1.5+12
The wood that we are using is 0.75" thick
The 1.5 that you see in the formula is the thickness
of the wood.
Calculating thickness of wood:
Measure how thick the wood is then multiply by two.
The reason that you are multiplying by two is each
side of the enclosure.
Left + Right=1.5
Top + Bottom=1.5
Front + Back=1.5
.75 x 2=1.50
18 x 12 x 10.5=2268
2268 / 1728=1.3
1.3 cu. ft. is the results for this enclosure
