Question

An illustration shows a net version of a triangular prism. The net model shows 3 rectangles top to bottom. Identical triangles are attached to the left and right of the middle rectangle. Parts are labeled with measurements. The top and bottom rectangles have a length measuring 10 centimeters and a width measuring 5 centimeters. The perpendicular height from the top vertex of the triangle to the base measures 4 centimeters. The base of the triangle measures 5 centimeters. The base shares an edge with the middle rectangle.

What is the surface area of the net of the triangular prism?

(1 point)
(Blank) square centimeters

Answer 1

Surface area of the net of the triangular prism = 2(10 * 5) + 2(5 * 4) + 2(4 * 5) + 5 * 4
= 100 + 40 + 40 + 20
= 200 square centimeters

The surface area of the net of the triangular prism is 200 square centimeters.
