Part A: rectangular prism.

What makes it a rectangular polyhedron? Because the length is longer than the width?

Was what I said right about part A?

And I think part B was asking if it was a regular polyhedron or not haha

anonymous · Answer

No, it's a polyhedron due to the geometric shape of a rectangular prism. All prism have flat surfaces and straight edges. that's why prisms are considered to be polyhedrons. That's the main characteristic of being a polyhedron.

For part B, it's a polyhedron, but it's NOT a regular polyhedron.


In order for a polyhedron to be a regular polyhedron, all of its faces need to be congruent polygons. Since that's not the case here, it's not a regular polyhedron.

Ah, @jim_thompson5910 is absolutely correct. I missed that. Thanks for correcting me. @missashleyn, it's not a regular polyhedron for the reasons stated above by @jim_thompson5910
