To find the surface area of a triangular prism, we need to calculate the area of each face and then add them together.
- The triangular faces:
The base of the triangle is 15cm and the height is 8cm.
Area of triangle = 1/2 * base * height
Area = 1/2 * 15 * 8 = 60 cm^2 (There are two triangular faces, so total area for both is 2 * 60 = 120 cm^2)
- The rectangular faces:
The length of the rectangle is 12cm and the width is 15cm.
Area of rectangle = length * width
Area = 12 * 15 = 180 cm^2 (There are three rectangular faces, so total area for all is 3 * 180 = 540 cm^2)
Adding up the areas of the triangular and rectangular faces:
Total surface area = 540 + 120 = 660 cm^2
Therefore, the correct answer is 603.16cm^2.
