Answer: 105 square units

Step-by-step explanation: To find the surface area of a triangular prism, you need to find the area of each face and add them together.

In this case, the triangular bases have the same area, which is:

(1/2) x 7 x 5 = 17.5 square units

The rectangular faces have an area of:

7 x 10 = 70 square units

Adding the areas of all the faces, we get:

17.5 + 17.5 + 70 = 105 square units

Therefore, the surface area of the triangular prism is 105 square units.
