An illustration shows a two-dimensional net of a triangular prism with all of its sides open and visible. The net appears as three vertical rectangles joined next to each other. All 4 sides of the middle rectangle are drawn with dashed lines. The width of the rectangles is 6 centimeters. The length of the middle rectangle is 8 centimeters. Two identical triangles adjoin the middle rectangle at the top and bottom with sides each measuring 8 centimeters and the perpendicular height measuring 6.9 centimeters.

The net of the triangular prism shows how the three rectangles can be folded to form the prism. The dashed lines indicate where the edges would be folded to create the solid shape. The triangles are attached at the top and bottom of the middle rectangle to form the three-dimensional shape of the prism. Each triangle has a base of 8 centimeters and a perpendicular height of 6.9 centimeters.
