Answer:
Lateral surface area formula: AL=(a+b+c)h
Step-by-step explanation:
"Finds the total area contained by the three rectangular sides of the prism. You can think of the lateral surface area as the total surface area of the prism minus the two triangular areas at the top and bottom of the prism."
Ok, so you can just ignore that 8.7 ft (height of triangle shape). It's not important for finding the lateral surface area.
a, b, c are the base sides. You add the sides of a triangle.
Multiply (a+b+c) with the height, h.
(10 + 10 + 10) x 17 = ?
[this formula can apply for ANY triangular prism no matter which position it's shown]
ANSWER: 510 ft^2
