A square prism has square?
A square prism is a solid object with identical ends, flat sides, and has the same cross section through out its length.
What is the intersection of a plane and a solid?
It is a cross section.
How can you the volume of a rectangular solid?
Volume = cross-section area*length
What solid has 7 faces 10 vertices and 15 edges?
A prism that has pentagonal cross-section
What solid has a triangular cross section when the cross section is taken perpendicular to the base?
A solid with a triangular cross section when the cross section is taken parallel to the base could be either a triangular prism, a triangular pyramid, or a triangular frustrum.. I've been sitting here trying to convince myself (without actually bearing down and trying to prove it mathematically) that any cross section of a regular tetrahedron (a special case of triangular pyramid) taken perpendicularly to the base is a triangle, and I THINK this is the case, but as I said I certainly haven't rigorously proven it; I'm just unable to come up with any obvious situation where this is not true.
