Chapter 12.8, Problem 13IP

To determine

To find : Surface area of prism shown.

Answer to Problem 13IP

  $656{\text{m}}^{\text{2}}$

Explanation of Solution

Given information :

The given information is,

  

Formula Used:

Area of Rectangular prison = $2(lb+bh+hl)$

Area of triangular prism = $ph+2B$

Calculation :

Area of Rectangular prison,

  $\begin{array}{l}{A}_R=2(8\times 8+8\times 10+10\times 8)=448{\text{ m}}^{\text{2}}\\ A_T=(4+8+10)\cdot 8+2\frac{1}{2}\cdot 8\times 4=208{\text{ m}}^{\text{2}}\end{array}$

Total surface area = $656{\text{m}}^{\text{2}}$
