Volume & Surface Area Calculator

For Common 3D Shapes

Formulas for a Cylinder

  • Volume: V = πr²h
  • Surface Area: A = 2πrh + 2πr²

How the Volume and Surface Area Calculator Works

Volume measures the space inside a 3D object (cubic units like m³). Surface Area measures the total area covering the outside of a 3D object (square units like m²). Both are essential in construction, manufacturing, and packaging.

Key Differences

  • Volume: Space inside, Cubic units (m³, ft³), Capacity measurement
  • Surface Area: Outer covering, Square units (m², ft²), Material needed

Common 3D Shapes

Cube & Rectangular Prism

  • Volume: V = length × width × height (Cube: V = s³)
  • Surface Area: SA = 2(lw + lh + wh) (Cube: SA = 6s²)

Sphere

  • Volume: V = (4/3)πr³
  • Surface Area: SA = 4πr²

Cylinder

  • Volume: V = πr²h
  • Surface Area: SA = 2πr² + 2πrh

Cone & Pyramid

  • Volume: V = (1/3) × base area × height (Cone: V = (1/3)πr²h)
  • Surface Area: Cone: SA = πr² + πrl (l = slant height)

Real-World Applications

Packaging & Shipping

Volume determines capacity, surface area determines material needed for boxes and containers.

Construction

Calculate concrete needed (volume) and paint required (surface area) for building projects.

Manufacturing

Design products with optimal volume-to-surface-area ratios for efficiency and cost savings.

Storage & Capacity

Design tanks, pools, and storage units with the right capacity and coating requirements.
