How to find the surface area of a right triangular prism?
We find the sum of areas of all the sides and faces of a right triangular prism to determine its surface area.
Answer: The formula to calculate the surface area of a right triangular prism is given by S1 × h + (S1 + S2 + h) L
A right triangular prism is a three-dimensional solid that has three rectangular sides and two right triangular faces.
Explanation:
The formula to calculate the surface area of a right triangular prism is given as S1 × h + (S1 + S2 + h) L
Here, 'h' is the height of the base triangle, S1 is the base edge, S2 is the hypotenuse and L is the base length of the prism as shown in the figure.
Let us take an example to find the surface area of a right triangular prism. Let the base of a right triangle be 5 units, the height of the triangle be 12 units, the length of a prism be 11 units and the hypotenuse of a right triangle be 13 units.
Surface area of a right triangular prism = 5 × 12 + (5 + 13 + 12) × 11 squared units
= 60 + (30) ×11 squared units
= 390 squar units
