An illustration shows a two-dimensional net of a triangular prism with all of its sides open and visible. The net appears as a rectangle, a square, and another rectangle joined horizontally next to each other. The width of the two rectangles and the side of the square measure 3 centimeters. The length of the left rectangle is 4 centimeters. The side of the middle square, drawn in a dashed line, is 3 centimeters. The length of the right rectangle is 5 centimeters. Two right triangles adjoin the middle square at the top and bottom, with each perpendicular side measuring 4 centimeters and each hypotenuse measuring 5 centimeters.
The net of the triangular prism can be unfolded to form a rectangle, a square, and another rectangle joined horizontally. The dimensions of each component are as follows:
- Left rectangle: 4 cm x 3 cm
- Middle square: 3 cm x 3 cm
- Right rectangle: 5 cm x 3 cm
- Right triangles: Each has two sides of 4 cm and one side of 5 cm
When these components are folded and joined together, they form a triangular prism with a base of a triangle and three rectangular faces.
