Formulas and Key Relations

Density

d = M / V

Unit of density = Unit of mass / Unit of volume

1 kg m^-3 = 10^-3 g cm^-3

1 g cm^-3 = 1000 kg m^-3

Density of Regular Solids

Volume of a cube = (one side)^3

Volume of a cuboid = length × breadth × height

Volume of a sphere = 4/3 π (radius)^3

Volume of a cylinder = π (radius)^2 × height

Irregular Solids and Displacement Method

V = (V2 - V1) cm^3
