Examples 
Formula 
Sphere 
The solid generated by revolving a circular alumina about any of its diameters, is called the sphere. 
Football, volleyball, etc., 

Volume = 4/3 πr^3

Surface area = 4π r^2

Cylinder 
The solid bounded by a circular curved surface and two identical bases. 
Circular pillars, circular pipes, circular pencils, measuring jars, road rollers and gas cylinder etc., 

Volume = π r^2 h

Curved surface area= 2 π r h

Total surface area= 2πr(r + h)

Cone 
The solid generated by the rotation of a right angled triangle about one of the sides containing the right angle is called a right circular cone. 
Icecream cone, conical vessel, clown’s cap, etc. 

Volume= (1/3)π r^2 h

Curved surface area= πr√( h^2 + r^2) = π r l

Total surface area= π r (l + r)

Cuboid 
A solid bounded by six rectangular faces is called a cuboid. 
Matchbox, chalk box, brick, tile, book, etc., 

Volume= l * b * h

Diagonal=√(l^2+b^2+h^2 )

Total surface area =2(lb+bh+lh)

Lateral surface area =2 ( l + b) * h

Cube 
A cuboid whose length, breadth and heights are all equal is called a cube. 
Dice, ice cubes, sugar cubes etc., 

Volume= a^3

Diagonal = √3 a

Total surface area= 6 a^2

Lateral surface area= 4 a^2
