VOLUME & SURFACE AREA OF THE SOLID - VOLUME OF CUBOID

__VOLUME & SURFACE
AREA OF THE SOLIDS –__

__Solids –__**Any shape of bodies or object occupying space is considered as solid. The solid
bodies occur in various shapes, such as cuboid , a cube, a cylinder, a cone,
and a sphere, etc.**

__Cuboid –__**A
rectangular solid bounded by six rectangular plane faces is called a cuboid. A match
box, a chalk box, a brick, a block, a book, etc., are all examples of a cuboid.
A cuboid has 6 rectangular faces, 12 edges and 8 vertices. Let us considered a
cuboid of length = l units, breadth = b units, and height = h units.**

__Volume of a Cuboid
–__

**The space enclosed by a cuboid is called its volume.**

**Volume of cuboid = (l X b X h) cubic units**

**Example.)
Find the volume of a
rectangular solid 10 m long, 5 m broad, and 70 cm high.**

**Ans.) As per the formulae, volume of the cuboid =
(l X b X h) cubic units**

** 70**

**Here, h
= ------- m [100 cm = 1 m, so 1 cm = 1/100 m]**

** 100**

** = 0.70 m**

**l = 10 m, b
= 5 m**

**now,
according to the formulae - **

**
(l X b X h) cubic unit = (10 X 5 X 0.70) m³ = 35 m³ (Ans.)**
