The surface area of the prism is 144 square units
How to determine the surface area?
The attached image represents the missing figure in the question.
The image would be used to complete the steps, as follows:
- Step 1: The surface area formula. Surface Area = BA + ph
- Step 2: The shape of the bases are right triangles
- Step 3: The area of one base; Area = 0.5 * 3 * 4 = 6
- Step 4: Multiply the area in (3) by 2: BA = 2 * 6 = 12
- Step 5: The perimeter of one base. p = 3 + 4 + 5 = 12
- Step 6: Multiply p by h; LA = 12 * 11 = 132
- Step 7: Add (4) and (6). Surface Area = 12 + 132 = 144
Hence, the surface area of the prism is 144 square units
