Given :
Dimensions of Brick
- ✰ Length of Brick = 12.5cm
- ✰ Breadth of Brick = 7.5cm
- ✰ Height of Brick = 5cm
___________
Dimensions of wall :
- ✰ Length of wall = 12.5m
- ✰ Breadth of wall = 15m
- ✰ Height of wall = 0.5m
To Find :
- ✰ Number of bricks
Solution :
- ✰ As in question Length, Breadth and height of a brick and a wall is given. So firstly we will convert dimensions of wall in cm. Then find the Volume of Brick and Wall that is Length × Breadth × Height. After Finding the volume of wall and Brick we Can easily find the number of bricks
Length of wall = 12.5m = 1250cm
Breadth of wall = 15m = 1500cm
Height of wall = 0.5m = 50cm
Volume of Brick = L × B × H
Where,
- Length (L) = 12.5cm
- Breadth (B) = 7.5cm
- Height (H) = 5cm
___________
➤ Volume of Brick = 12.5 × 7.5 × 5
➤ Volume of Brick = 93.75 × 5
➤ Volume of Brick = 468.75 cm
Volume of wall = L × B × H
Where,
- Length (L) = 1250cm
- Breadth (B) = 1500cm
- Height (H) = 50cm
___________
➤ Volume of wall = 1250 × 1500 × 50
➤ Volume of wall = 1875000 × 50
➤ Volume of wall = 93750000cm
Number of Brick required
➤ Volume of Wall/Volume of wall
➤ 93750000/468.75
➤ 200,0000
∴ Number of bricks are 200,0000
