Triangular Prism Area Calculator
What is a Triangular Prism?
A triangular prism is a three-dimensional solid object with two parallel triangular bases and three rectangular lateral faces connecting them. It is commonly found in architecture, construction, and design projects. Calculating the surface area of a triangular prism is essential for tasks such as painting, manufacturing, material estimation, and academic exercises.
Formula for Surface Area:
The surface area of a triangular prism is calculated as: Surface Area=2×Base Area+Perimeter of Triangle×Length of Prism\text{Surface Area} = 2 \times \text{Base Area} + \text{Perimeter of Triangle} \times \text{Length of Prism}Surface Area=2×Base Area+Perimeter of Triangle×Length of Prism
Where:
- Base Area = 12×base×height\frac{1}{2} \times \text{base} \times \text{height}21×base×height
- Perimeter of Triangle = sum of all three sides of the triangular base
Our calculator automatically handles these computations for you in seconds.
How to Use the Triangular Prism Area Calculator
Using this calculator is simple and straightforward. Follow these steps:
- Enter the Base of the Triangle:
Input the length of the triangle’s base in the first field. Ensure it’s a positive number. - Enter the Height of the Triangle:
Input the height corresponding to the base. This height is perpendicular to the base. - Enter the Length of the Prism:
Provide the length (or depth) of the prism. This determines the distance between the two triangular faces. - Click “Calculate”:
Press the Calculate button. The tool will instantly compute the surface area of your triangular prism. - View the Result:
The surface area will be displayed in square units. You can now use this value for your project or calculations. - Reset (Optional):
Click the Reset button to clear all inputs and start a new calculation.
Practical Example
Let’s see the tool in action with a real-world example:
- Base of Triangle: 5 units
- Height of Triangle: 6 units
- Length of Prism: 10 units
Calculation Steps Manually (for understanding):
- Triangle Area = 0.5×5×6=150.5 \times 5 \times 6 = 150.5×5×6=15 sq.units
- Triangle Sides = Base = 5, other sides (using Pythagoras) = (5/2)2+62≈6.71\sqrt{(5/2)^2 + 6^2} \approx 6.71(5/2)2+62≈6.71 each
- Triangle Perimeter = 5+6.71+6.71=18.425 + 6.71 + 6.71 = 18.425+6.71+6.71=18.42 units
- Surface Area = 2×15+18.42×10=30+184.2=214.22 \times 15 + 18.42 \times 10 = 30 + 184.2 = 214.22×15+18.42×10=30+184.2=214.2 sq.units
Using our calculator, the result 214.20 sq.units is displayed instantly without manual calculations.
