Volume
The volume of J35 can be calculated as follows:
J35 consists of 2 cupolae and hexagonal prism.
The two cupolae makes 1 cuboctahedron = 8 tetrahedra + 6 half-octahedra. 1 octahedron = 4 tetrahedra, so total we have 20 tetrahedra.
What is the volume of a tetrahedron? Construct a tetrahedron having vertices in common with alternate vertices of a cube (of side, if tetrahedron has unit edges). The 4 triangular pyramids left if the tetrahedron is removed from the cube form half an octahedron = 2 tetrahedra. So
The hexagonal prism is more straightforward. The hexagon has area, so
Finally

Famous quotes containing the word volume:
“F.R. Leaviss eat up your broccoli approach to fiction emphasises this junkfood/wholefood dichotomy. If reading a novelfor the eighteenth century reader, the most frivolous of diversionsdid not, by the middle of the twentieth century, make you a better person in some way, then you might as well flush the offending volume down the toilet, which was by far the best place for the undigested excreta of dubious nourishment.”
—Angela Carter (19401992)
“And all the great traditions of the Past
They saw reflected in the coming time.
And thus forever with reverted look
The mystic volume of the world they read,
Spelling it backward, like a Hebrew book,
Till life became a Legend of the Dead.”
—Henry Wadsworth Longfellow (18091882)
“She carries a book but it is not
the tome of the ancient wisdom,
the pages, I imagine, are the blank pages
of the unwritten volume of the new.”
—Hilda Doolittle (18861961)
