Question

Any polyhedron can be the base of a pyramid.\

A. True
B. False

Answer 1

False, A polyhedron is a solid object whose having a number of polygonal faces.

The base of a pyramid could not be a solid object but instead a flat surface of having finite number of sides which is called polygon.

Answer 2

B. False

Explanation:

The statement is false, because a pyramid has an two-dimensional figure at its base, you can see this by observing the equation for a pyramids volume:

`V=(1)/(3)A_(base)h`

Where
`A_(base)` is a two-dimensional shape, like a triangle, rectangle, polygon.

So, the reason why is false, is because a polyhedron is a three-dimensional figure, it's now two-dimensional, so it can't be in the base of a pyramid, because it won't form a pyramid.
