Key Concepts
Volume is the amount of space enclosed by a 3D object.
Cube
V = a³
V = a³
a = edge length
Volume = a³
Volume = a³
Cylinder
V = πr²h
V = πr²h
r = radius, h = height
Volume = πr²h
Volume = πr²h
Interactive Models
Cube
V = a³
Where:
a = edge length
V: 125 cm³
Cylinder
V = πr²h
Where:
r = radius, h = height
V: 392.7 cm³
Sphere
V = 4/3πr³
Where:
r = radius
V: 0 cm³
Cone
V = 1/3πr²h
Where:
r = radius, h = height
V: 0 cm³
Practice Problems
A cube has edge length 3cm. Calculate its volume.
V = a³ = 3³ = 27 cm³
A cylinder with radius 2cm and height 5cm. Find its volume.
V = πr²h = π×2²×5 = 20π ≈ 62.8 cm³
