Solution Methodology
01
Enter Dimensions
Input the three sides of the triangular base and the length of the prism.
02
Compute Base Area
Calculate the area of the triangular bases using Heron's formula.
03
Compute Lateral Area
Multiply the perimeter of the triangle by the prism length, then sum for total area.
Common Questions
How do you find the surface area of a triangular prism?
Calculate the area of the two triangular bases, and then calculate the area of the three rectangular sides connecting them. Sum all five areas for the total surface area: SA = 2 × (Base Area) + (Perimeter of Base) × Length.
What is the lateral area of a triangular prism?
The lateral area is the area of the three rectangular sides only, excluding the triangular bases. It is calculated by multiplying the perimeter of the triangular base by the length of the prism.
