Triangular Prism Calculator
A prism is defined as a 3dimensional solid object which has identical ends, flat faces, and the same crosssection all along its length. A triangular prism is defined as a threedimensional shape, having its bases as triangles.

How to Find the Triangular Prism Calculator?
The surface area of the triangular prism is the sum of the base area and lateral faces. let a,b, and c are sides of a triangle and triangle base be 'B', the height of triangle be 'h' and height of prism be 'H'.
Surface area of the triangular Prism = (2 × base area of a triangle) + (perimeter of the base × height of the prism)
= {2 × (½ × B × h)} + {(a + b + c) × H}
= (B × h) + {(a + b + c) × H}
The volume of the triangular prism is defined as the capacity of the triangular prism or the measure of the amount of space it occupies and it is measured in cubic units. The volume of the triangular prism whose base length is 'B', and the height of the triangle is 'h', and 'l' is the distance between the bases or height of the triangles of the prism is calculated by the following formula:
The volume of triangular prism = Base Area × height of the prism = 1/2 × (B × h) × l
Let us now better understand the formulas to find the surface area and volume of a triangular prism by solving an example.
Solved Examples on Triangular Prism Calculator

Example1:
Find the surface area of a triangular prism having sides of a triangle 2,3 and 4 units and the triangle base is 5 units, the height of the triangle is 6 units, and the height of the prism is 7 units.
Solution:
Surface area of the triangular prism = (2 × base area of a triangle) + (perimeter of the base × height of the prism)
= {2 × (½ × B × h)} + {(a + b + c) × H}
= (B × h) + {(a + b + c) × H}
= (5 × 6) + {(2 + 3 + 4) × 7}
= 30 + {9 × 7}
= 30 + 63
= 93 square units

Example2:
Find the volume of the triangular prism whose base length is 5 units, the height of a triangle is 6 units, and the height of the prism is 7 units?
Solution:
Given: l = 7 units, b = 5 units, and h = 6 units
The volume of triangular prism = Base Area × height of the prism = 1/2 × (b × h) × l
= 1/2 × (5 × 6) × 7
= 105 cubic units
