Volume measures the amount of 3-dimensional space occupied by an object, calculated using specific formulas for different geometric shapes.
What is Volume?
Volume is the measure of the amount of three-dimensional space occupied by a solid object. It quantifies how much space an object takes up and is typically measured in cubic units (such as cubic meters, cubic centimeters, or cubic feet). Volume calculations are essential in mathematics, physics, engineering, and everyday life for determining capacity, displacement, and material requirements.
Volume Formulas
Cube
All sides equal
s = side length
Sphere
Perfectly round
r = radius
Cylinder
Circular base
h = height
Cone
Pointed top
1/3 of cylinder
Volume Calculation Rules
1. Cube Volume
The volume of a cube with side length s is:
V = s × s × s = s³
2. Sphere Volume
The volume of a sphere with radius r is:
V = (4/3) × π × r³
3. Cylinder Volume
The volume of a cylinder with radius r and height h is:
V = π × r² × h

Step-by-Step Calculation Process
Example 1: Cube with side 5 units
- Identify shape: Cube
- Formula: V = s³
- Substitute: V = 5³
- Calculate: 5 × 5 × 5 = 125
- Volume = 125 cubic units
Example 2: Sphere with radius 3 units
- Identify shape: Sphere
- Formula: V = (4/3)πr³
- Substitute: V = (4/3) × π × 3³
- Calculate: 3³ = 27
- Multiply: (4/3) × 27 = 36
- Final: 36 × π ≈ 113.1 cubic units

Frequently Asked Questions (FAQs)
Q: What's the difference between volume and capacity?
A: Volume is the total space occupied by an object, while capacity refers to the amount a container can hold. They're often used interchangeably but capacity typically refers to liquids a container can hold.
Q: How do I convert between different volume units?
A: Use conversion factors: 1 liter = 1,000 cm³, 1 m³ = 1,000 liters, 1 gallon ≈ 3.785 liters. Multiply or divide by these factors to convert between units.
Q: Can volume be negative?
A: No, volume is always a positive quantity or zero. It represents the amount of space occupied, which cannot be negative.
Q: Why is the volume of a cone 1/3 of a cylinder with same dimensions?
A: This relationship comes from calculus integration. A cone can be thought of as a cylinder whose cross-sectional area decreases linearly from base to tip, resulting in exactly 1/3 the volume.
