faces= seven edges=fifteen vertices=ten
A hexagonal prism . It has 6 sides to the hexagon, plus a top an dbottom.An octagonal prism is based on an eight-sided figure but is actually ten-sided
19 * * * * * Actually it is 30 edges. Ten around each of the decagonal faces, and ten more connecting the corresponding vertices of the two decagons.
A pentagonal prism.
In geometry, the decagonal prismis the eighth in the infinite set of prisms, formed by ten square side faces and two regular decagon caps. With twelve faces, it is one of many non-regular dodecahedra.
There are 10 parallel lateral edges. And ten parallel edges between the two bases. There could be more - within each decagon, but that depends on the decagons, and details of these are not given.
A pyramid with an n-sided base will have n + 1 vertices, n + 1 faces, and 2n edges.
In geometry, a decahedron is a polyhedron with ten faces. There are 32300 topologically distinct decahedra and none are regular, so this name is ambiguous.One regular decahedron is an octagonal prism. Along with its 10 faces, it has 16 vertices and 24 edges.
Uhh, 10 sides. It's a TEN SIDED POLYGON and you're asking how many sides it has? You answered the question yourself.
A ten sided figure is a decahedron.
ten
Ten of them
