Any polyhedron can be the base of a pyramid.\ a. true b. false

Step-by-step 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:

Where 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.

$4

step-by-step explanation:

$30×5=$150

$150 minus $130=$20

$20÷5=$4.
