Chapter 12.8, Problem 2GP

To determine

To find : Lateral and surface area of each prism.

Answer to Problem 2GP

Lateral surface Area = $360{\text{mm}}^{\text{2}}$ and Surface Area = $420{\text{mm}}^{\text{2}}$

Explanation of Solution

Given information :

The given information is, as given $a=8,b=15,c=17$ and $h=9$

  

Formula Used:

Lateral surface area of prism = $(a+b+c)\times h$

Surface area of Prism = Lateral Area + $2$ B

Where, B = Base Area

Calculation :

Lateral Surface Area = $(8+15+17)\times 9=360{\text{mm}}^{\text{2}}$

Surface Area of Prism = $360+\frac{1}{2}\times 15\times 8$

  $=420{\text{ mm}}^{\text{2}}$
