Ginny wants to decorate the gift she got for her friend by putting a rose on each vertex of the package. The package is in the shape of a rectangular pyramid. How many roses does she need?
A rectangular pyramid is what they built in Egypt thousands of years ago. The base is a rectangle, and it has one top. So the sides are triangles. The base has 4 corners and then there's the top. That makes a total of 5 points (or vertices).
