To find the area of a triangular prism, you need to calculate the area of the three faces (two triangular faces and one rectangular face) and then add them together.
1. Calculate the area of the two triangular faces:
Area of triangle = 1/2 * base * height
First triangular face:
Area = 1/2 * 9 * 17 = 76.5 in²
Second triangular face:
Area = 1/2 * 12 * 17 = 102 in²
2. Calculate the area of the rectangular face:
Area = length * width
Area = 10 * 17 = 170 in²
3. Add the areas of the three faces together:
Total area = 76.5 + 102 + 170 = 348.5 in²
Therefore, the area of the triangular prism is 348.5 square inches.
what is the area of the triangle prism with the following dimensions 9 inch 17 inch 10 inch 12 inch 17 inch 10 inch.
