Question 1

How do I calculate the volume of a cube?

Accepted Answer

Volume of a cube = side³ (side × side × side). For example, a cube with side 5 cm has volume = 5³ = 125 cubic cm. All sides of a cube are equal.

Question 2

How do I calculate the volume of a sphere?

Accepted Answer

Volume of a sphere = (4/3) × π × radius³. For example, a sphere with radius 3 cm has volume = (4/3) × π × 27 ≈ 113.1 cubic cm.

Question 3

How do I calculate the volume of a cylinder?

Accepted Answer

Volume of a cylinder = π × radius² × height. For example, a can with radius 4 cm and height 10 cm has volume = π × 16 × 10 ≈ 502.7 cubic cm.

Question 4

What is the difference between area and volume?

Accepted Answer

Area measures 2D surface space (square units), while volume measures 3D space occupied (cubic units). A room has floor area in sq ft but volume in cubic ft for air capacity.

Question 5

How is volume used in real life?

Accepted Answer

Volume calculation is used for shipping (package dimensions), cooking (recipe measurements), swimming pools, fish tanks, tanks/containers, construction, and material estimation.
