Volume Formulas of Solid Figures

 

Some of the formulas to find out volumes of basic shapes are –

 

Shapes Volume Formula Variables
Rectangular Solid or Cuboid V = l × w × h l = Length,

w = Width,

h = Height

Cube V = a3 a = length of edge or side
Cylinder V = πr2h r = radius of the circular edge,

h = height

Prism V = B × h B = area of base, (B = side2 or length.breadth)

h = height

Sphere V = (4⁄3)πr3 r = radius of the sphere
Pyramid V = (1⁄3) × B × h B = area of the base,

h = height of the pyramid

Right Circular Cone V = (1⁄3)πr2h r = radius of the circular base,

h = height (base to tip)
