How to Find the Surface Area of a Triangular Prism?
A prism is defined as a 3-dimensional solid object which has identical ends, flat faces, and the same cross-section all along its length.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 × (1/2 × b × h)} + {(a + b + c) × H}
= (b × h) + {(a + b + c) × H}
Let us now better understand the formula to find the surface area of a triangular prism, by solving an example.
Solved Examples on Triangular Prism Surface Area Calculator
Example 1:
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
Therefore the surface area of a triangular prism is 93 square units.
Example 2:
Find the surface area of a triangular prism having sides of a triangle 5, 6 and 7 units and the triangle base is 8 units, the height of the triangle is 3 units, and the height of the prism is 2 units.
Solution:
Surface area of the triangular prism = (2 × base area of a triangle) + (perimeter of the base × height of the prism)
= {2 × (1/2 × b × h)} + {(a + b + c) × H}
= (b × h) + {(a + b + c) × H}
= (8 × 3) + {(5 + 6 + 7) × 2}
= 24 + {18 × 2}
= 24 + 36
= 60 square units
Therefore the surface area of a triangular prism is 60 square units.
Now, try the triangular prism surface area calculator to find the surface area of the following triangular prisms.
1) Sides of a triangle 4,5 and 6 units, the triangle base is 7 units, the height of the triangle is 8 units, and the height of the prism is 9 units.
2) Sides of a triangle 3,5 and 7 units and the triangle base is 5 units, the height of the triangle is 8 units, and the height of the prism is 11 units.
