What is a Right Triangular Prism?

A Right Triangular Prism is a three-dimensional solid that has two identical right-angled triangular faces and three rectangular faces. Imagine taking a right triangle and extending it along its length — that’s your prism.

It’s commonly seen in real-world applications such as:

  • Roof designs
  • Bridge trusses
  • Tents and sheds
  • Optical prisms and structural components

The geometry of the prism allows for easy computation of its physical attributes, which are essential in design, manufacturing, and education.

Key Measurements of a Right Triangular Prism

A right triangular prism has the following important measurements:

  1. Base (b) – The base of the right triangle.
  2. Height (h) – The vertical side of the right triangle.
  3. Length (L) – The distance between the two triangular ends.

With these three values, you can calculate:

  • Base Area
  • Volume
  • Surface Area

Formulas Used in the Right Triangular Prism Calculator

Here are the simple mathematical formulas this calculator uses:

  1. Base Area (A₍base₎) = ½ × base × height Abase=12×b×hA_{base} = \frac{1}{2} \times b \times hAbase​=21​×b×h
  2. Volume (V) = Base Area × Length V=Abase×LV = A_{base} \times LV=Abase​×L
  3. Surface Area (S) = (Base × Length) + (Height × Length) + (Hypotenuse × Length) + (2 × Base Area) S=(bL)+(hL)+(b2+h2×L)+(2Abase)S = (bL) + (hL) + (\sqrt{b^2 + h^2} \times L) + (2A_{base})S=(bL)+(hL)+(b2+h2​×L)+(2Abase​)

These formulas allow the calculator to instantly compute all required results.

Example Calculation

Let’s understand it with a practical example:

Given:

  • Base (b) = 5 cm
  • Height (h) = 4 cm
  • Length (L) = 10 cm

Step 1: Find the Base Area Abase=12×5×4=10 cm2A_{base} = \frac{1}{2} \times 5 \times 4 = 10 \, cm^2Abase​=21​×5×4=10cm2

Step 2: Find the Volume V=10×10=100 cm3V = 10 \times 10 = 100 \, cm^3V=10×10=100cm3

Step 3: Find the Surface Area S=(5×10)+(4×10)+(52+42×10)+(2×10)S = (5 \times 10) + (4 \times 10) + (\sqrt{5^2 + 4^2} \times 10) + (2 \times 10)S=(5×10)+(4×10)+(52+42​×10)+(2×10) S=50+40+(6.40×10)+20=174 cm2S = 50 + 40 + (6.40 \times 10) + 20 = 174 \, cm^2S=50+40+(6.40×10)+20=174cm2

✅ Final Results:

  • Base Area = 10 cm²
  • Volume = 100 cm³
  • Surface Area = 174 cm²
