Volume And Surface Area Calculator
Volume And Surface Area - Solve mathematical problems with step-by-step solutions.
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.
