Surface Areas and Volumes – Notes
Cube and Cuboid
A solid figure bonded by six rectangular plane faces is called a cuboid.
It is also known as rectangular prism
A cuboid in which length, breadth and height are equal is called a cube.
Surface Area or Total Surface Area of a cuboid = 2(ɭb + bh + ɭh)
Surface Area or Total Surface Area of a cube = 6a2
Lateral Surface Area or Area of four walls of a cuboid = 2(ɭ + b)h
Lateral surface area of a cube = 4a2
Volume of cboid = ɭbh
Volume of a cube = a3
