Question

Select the letter that correctly identifies the base of the prism.A. cB. dC. bD. a

Answer 1

D. a

Step-by-step explanation

A prism has two faces that are equal. These are called base and top (usually referred to as base as well), and their shape defines the name of the prism - for example, triangular prism or rectangular prism.

The other faces are all rectangles.

In this figure, we can see that b, c, and d are rectangular faces, so none of these is the base. Hence, a is the base of the prism.
