Surface Area Triangular Prism Calculator
What is a Triangular Prism?
A triangular prism is a three-dimensional solid with two parallel triangular bases connected by rectangular faces. The main properties of a triangular prism include:
- Base: The length of one side of the triangular base.
- Height of Triangle: The perpendicular height of the triangular base.
- Length of Prism: The distance between the two triangular bases.
The surface area of a triangular prism is the total area of all its faces: both triangles and the three rectangular sides.
Mathematically, the surface area SASASA is calculated as: SA=2×(Triangle Area)+(Perimeter of Triangle×Prism Length)SA = 2 \times (\text{Triangle Area}) + (\text{Perimeter of Triangle} \times \text{Prism Length})SA=2×(Triangle Area)+(Perimeter of Triangle×Prism Length)

Example Calculation
Let’s see the calculator in action with a practical example:
- Base of Triangle: 5 units
- Height of Triangle: 4 units
- Length of Prism: 10 units
Step 1: Calculate Side Length of Triangle Side Length=(Base2)2+Height2=(2.5)2+42=6.25+16=22.25≈4.72\text{Side Length} = \sqrt{(\frac{\text{Base}}{2})^2 + \text{Height}^2} = \sqrt{(2.5)^2 + 4^2} = \sqrt{6.25 + 16} = \sqrt{22.25} \approx 4.72Side Length=(2Base)2+Height2=(2.5)2+42=6.25+16=22.25≈4.72
Step 2: Calculate Triangle Area Triangle Area=Base×Height2=5×42=10\text{Triangle Area} = \frac{\text{Base} \times \text{Height}}{2} = \frac{5 \times 4}{2} = 10Triangle Area=2Base×Height=25×4=10
Step 3: Calculate Lateral Area Lateral Area=3×Side Length×Length=3×4.72×10≈141.6\text{Lateral Area} = 3 \times \text{Side Length} \times \text{Length} = 3 \times 4.72 \times 10 \approx 141.6Lateral Area=3×Side Length×Length=3×4.72×10≈141.6
Step 4: Calculate Surface Area Surface Area=2×Triangle Area+Lateral Area=2×10+141.6=161.6 sq units\text{Surface Area} = 2 \times \text{Triangle Area} + \text{Lateral Area} = 2 \times 10 + 141.6 = 161.6 \text{ sq units}Surface Area=2×Triangle Area+Lateral Area=2×10+141.6=161.6 sq units
The calculator automates all these steps, saving time and reducing errors.
