hey bro ruko mere question ka answer de ke jao..
1.The platform at the base of the statue is to be built to a height of 1.5m on a square base measuring 2m by 2m. It is to be constructed from bricks of dimention 25cm ,15cm & 10cm .How many bricks will be required to build the base of the statue??
pls don't ans for few points
I need answer from retired aryabhatt..

Given :
- Dimensions of platform are 1.5m, 2m and 2m
- Dimensions of bricks are 25cm, 15cm and 10cm.
To find :
- Number of bricks required to build the base of statue.
Solution :
Length of cuboidal platform, l = 2m
Breadth of cuboidal platform, b = 2m
Height of cuboidal platform, h = 1.5m
Volume of cuboid = l * b * h
⇒ Volume of platform = 2 * 2 * 1.5
⇒ Volume of platform = 6 m³
Now, length of brick, l = 25 cm = 25/100 m = 0.25m
Breadth of brick, b = 15 cm = 15/100 m = 0.15m
Height of brick, h = 10 cm = 10/100 m = 0.1m
⇒ Volume of brick = (0.25 * 0.15 * 0.1) m³
⇒ Volume of brick = 3.75 × 10⁻³ m³
Now number of bricks required :
Number of bricks = Volume of platform/Volume of brick
⇒ Number of bricks = 6/(3.75 × 10⁻³)
⇒ Number of bricks = 1600
Therefore,
Number of bricks required = 1600
The length of the square base of the platform, l = 2m
The breadth of the square base of the platform, b = 2 m
The height of the platform, h = 1.5 m
∴ The volume of the cuboidal platform = l*b*h = 2 * 2 * 1.5 = 6 m³ …… (i)
The dimensions of 1 brick = 25cm*15cm*10cm
So, length = 0.25 m
Breadth = 0.15 m
Height = 0.10 m
∴ The volume of the 1 brick = length*breadth*height = 0.25 * 0.15 * 0.10 = 3.75 * 10⁻³ m³ …… (ii)
The no. of bricks that are required to build the base of the statue is,
= [Volume of the cuboidal platform] / [Volume of the 1 brick]
= 6 / [3.75 * 10⁻³]
= 1.6 * 10³
= 1600
