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 decagonal prism is a three-dimensional geometric shape that has ten faces, two of which are decagons (10-sided polygons) and the rest are rectangular. All the faces are congruent to each other, meaning they have the same size and shape. The prism has 20 edges and 12 vertices.
A pentagonal prism.
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 octagonal prism has 16 verticies,10 faces and 24 edges.
A ten sided figure is a decahedron.
All convex ten-faced polyhedra meet this criteria, and perhaps other polyhedra as well. There are several solutions, including: the polyhedron the half truncated cube: it has 24 edges.The octahedral prism has 24 edges.The square anti-prism 16 edges.The pentagonal bipyramid has 15 edges.The nonagonal pyramid has 18 edges.
