L/W = 1.000 P/W = 0.511 C/W = 0.329
H/W = (P+C)/W+0.02 = 0.860
P/H = 0.594 C/H = 0.382
Vol./W^3 = 0.396

Addition # 3 – This is fun to cut, there are no meets on the top after C3. Cut them as square as you can. This design has a lot of sparkle, you will be surprised. Cut in about any color and size… Cut in refractive indexes 1.73 (83.1%) to 2.14 with no changes.
