Question

What is the lateral area of a triangular prism with base edges all equaling 4 feet and a height of 10 feet?

160 ft2

180 ft2

140 ft2

120 ft2

Answer 1

Each lateral face is a rectangle with base 4 and height 10. So the area of one lateral face is 4*10 = 40 square feet

There are 3 lateral faces. So the total lateral surface area is 40*3 = 120 square feet.
