L/W = 1.000 T/W = 0.198 T/L = 0.198
P/W = 0.435 C/W = 0.229
H/W = (P+C)/W+0.02 = 0.684
P/H = 0.636 C/H = 0.335
Vol./W^3 = 0.224

Addition # 9 - Hint: It is helpful to leave the C3 a little short, then cut in the C4 tier and rough the table. Touch up the C3 tier as needed. This cuts fast and is simple, it is ideal for medium saturated material. Cut in refractive indexes 1.54 to 1.76 with no changes.
