Volume of a cube with side 5 cm:

Answer: 125 cm³.

  • A 25 cm³
  • B 75 cm³
  • C 125 cm³
  • D 150 cm³

Correct answer: C. 125 cm³

Explanation: Volume of cube = side³ = 5³ = 125 cm³.

Cylinder, Cone, SphereV=πr²hCSA=2πrhV=⅓πr²hCSA=πrlV=4/3πr³SA=4πr²

Three standard 3D solids and their key formulas: a cylinder's volume scales with the full height, a cone's volume is exactly one-third of the cylinder with the same base and height, and a sphere's volume and surface area both follow distinct r-based formulas worth memorising separately.
