1. Calculate the Surface Area of each of the following triangular-based prisms.

a)
The diagram shows a right-angled triangular base with legs 30 cm and 48 cm. The length of the prism is 60 cm. The label "25 cm" is ambiguous; we will assume the legs are 30 cm and 48 cm, and the prism length is 60 cm.

Step 1: Calculate the length of the hypotenuse of the triangular base using the Pythagorean theorem.

$$c^2 = a^2 + b^2$$ $$$$
