Disphenocingulum Calculator

Calculations at a disphenocingulum (translates as double wedge belt), the Johnson solid J₉₀. This is a polyhedron of 20 equilateral triangles and 4 squares. Two squares each are adjacent and form the two wedges.
Enter one value and choose the number of decimal places. Then click Calculate.

	Edge length (a):			24 faces, 38 edges, 16 vertices
	Surface area (A):
	Volume (V):
	Surface-to-volume ratio (A/V):
	Round to   0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15   decimal places.

The length has an one-dimensional unit (e.g. meter), the area has this unit squared (e.g. square meter), the volume has this unit to the power of three (e.g. cubic meter). A/V has this unit ^-1.
