Chapter 12.1, Problem 13WE

To determine

To find: the lateral area of a right pentagonal prism.

Answer to Problem 13WE

The lateral area of a right pentagonal prism is $390$ .

Explanation of Solution

Given information:

Height of the prism is $13$ and the base edges are $3.2,5.8,6.9,4.7,9.4$ .

Calculation: to find the lateral area, add the all the base edges and then multiply with the height,

  $\begin{array}{l}L.A.=\left(3.2+5.8+6.9+4.7+9.4\right)\left(13\right)\\ L.A.=\left(30\right)\left(13\right)\text{ [add]}\\ L.A.=390\text{ [multiply]}\end{array}$

Thus, The lateral area of a right pentagonal prism is $390$ .
