Interactive geometry — Volume & Surface Area of a Right Triangular Prism
← Back to HomeFormulas
Base Area (B) = ½ab
Volume (V) = ½abh
Hypotenuse (c) = √(a² + b²)
Perimeter (P) = a + b + c
Lateral SA (L) = P × h
Total SA (T) = ab + (a + b + c)h
How to Use
• Drag to rotate the prism in 3D
• Scroll to zoom in / out
• Adjust sliders to change dimensions
• Watch measurements update in real-time
Key Terms
Base — the triangular face (right triangle)
Legs (a, b) — the two perpendicular sides of the triangle
Hypotenuse (c) — the longest side opposite the right angle
Height (h) — the distance between the two triangular bases
Lateral Faces — the three rectangular faces
Did You Know?
Triangular prisms are used in optics to disperse white light into a rainbow spectrum — Isaac Newton's famous prism experiment in 1666 revealed that white light is composed of all colors.
