6) Find the lateral surface area. Round to the nearest tenth."10 points8 in.8 in.11 in.6.9 in.8 in.264274ОООО284204

Answer 1

264 in²

1) The lateral surface area excludes the bases

2) Since it is a triangular prism, let's calculate the area of those rectangles:

$\begin{gathered} S=3(w\cdot l) \\ S=3(8\times11) \\ S=3(88) \\ S\text{ =}264 \end{gathered}$

3) So the lateral surface area is 264 in²
