Final answer:
The formula for calculating the surface area of a right triangular prism is (Base × Height) + (2 × (Triangle Side × Height)).
Step-by-step explanation:
The formula for calculating the surface area of a right triangular prism is:
Surface Area = (Base × Height) + (2 × (Triangle Side × Height) )
Here, the Base and Triangle Side refer to the dimensions of the triangular faces of the prism, and the Height refers to the perpendicular height of the prism.
For example, if the base of the triangular face has a length of 5 units, the height of the triangular face is 8 units, and the height of the prism is 10 units, the surface area would be: Surface Area = (5 × 8) + (2 × (5 × 10)) = 40 + 100 = 140 square units.
