Question

Help find lateral area and surface area of the right prism please. Round answers to nearest hundredth if necessary.

Answer 1

lateral area

`A=Ph`

to find the missing side of the triangle we have

`\begin{gathered} 3^2+8^2=x^2 \\ 9+64=x^2 \\ 73=x^2 \\ x=\sqrt[]{73} \\ x=8.5 \end{gathered}`

so,

`\text{Alateral}=(3+8+8.5)*9.1=19.5*9.1=177.45m^2`

answer: 177.45 sq m

surface area
