Volume
Triangular Prism(Right Angle Triangle)
The volume of a triangular prism, V = AL
Where, A is the area of the cross-section of the prism.That is the area of one of the triangles, 
And, L is the length of the triangular prism.
Example
Pyramid
A pyramid is an object which has: a straight sided shape base (a squared, rectangular, trianglular base etc) and triangular sides which meet at the top (called the apex).
The volume of a pyramid, V = 
Where, A is the area of the base of the pyramid
And, h is the perpendicular height of the pyramid.
Example
Cylinder
The volume of a cylinder, V = πr2h
Where, πr2 is the area of the circular cross-section
And, h is the height of the cylinder.
Example
Volume of a cylinder, V = πr2h
Cube
The volume of a cube , V = L3
Where, L is the length of a side of the cube.
Example
Cuboid
The volume of a cuboid, V = Lwh
Where, L is the length of the cuboid
w is the width of the cuboid
And, h is the height of the cuboid.
Sphere
A sphere is a three-dimensional object (such as a ball or the earth) with every point on the surface equidistant (halfway from) from the center.
The volume of a sphere, V = 
πr3
Where, r is the radius of the sphere.
Example
Volume of a sphere, V = πr3
