We need to first find the area of each triangle face and the rectangular lateral face.

To find the area of a triangle, we need to use the formula: A = (1/2)bh, where b is the base and h is the height.

For the two triangular faces, we have:

A = (1/2)(5)(3) = 7.5 cm²

(Note that the base is 5 cm because that is the length of one edge, and the height is 3 cm because that is the height of the prism.)

So the total area of the two triangular faces is 2(7.5) = 15 cm².

To find the area of the rectangular lateral face, we need to use the formula: A = lw, where l is the length and w is the width.

For the rectangular lateral face, we have:

A = (11)(5) = 55 cm²

(Note that the length is 11 cm because that is the length of the prism, and the width is 5 cm because that is the same as the length of one edge of the triangle.)

So the total surface area of the triangular prism is:

15 + 55 = 70 cm²

Therefore, the surface area of the triangular prism is 70 cm².
