🏛️ Understanding Pyramid Surface Area
A rectangular pyramid's surface area includes the rectangular base and four triangular faces. Each pair of opposite triangular faces has the same area.
Essential Formulas:
Base Area: A_base = a × b
Slant Heights: s₁ = √(h² + (b/2)²), s₂ = √(h² + (a/2)²)
Lateral Area: A_lateral = a×s₁ + b×s₂
Total Surface Area: SA = A_base + A_lateral
Volume: V = ⅓ × base area × height
🌍Real-World Applications
🏛️ 🏛️ Architecture & Manufacturing
Structural and industrial applications
❓Frequently Asked Questions
How do I calculate the slant heights for a rectangular pyramid?
A rectangular pyramid has two different slant heights:
For length faces: s₁ = √(h² + (width/2)²)
For width faces: s₂ = √(h² + (length/2)²)
Each slant height is the distance from the apex to the midpoint of a base edge.
What's the difference between lateral and total surface area?
Lateral Surface Area: Only the four triangular faces
Total Surface Area: Base + all four triangular faces
For most applications, "surface area" refers to the total surface area including the base.
