we are asked to find the surface area of a prism. To do that, we will find the areas of each lateral rectangle and the areas of the top and bottom triangles.
The areas of the rectangles are:
[tex]\begin{gathered} A_1=(10)(6)=60 \\ A_2=(10)(6)=60 \\ A_3=(10)(50)=50 \end{gathered}[/tex]
To determine the ara of the top triangle we will use the following formula:
[tex]undefined[/tex]
