# How Many Bricks of Length 25 Cm, Breadth 15 Cm and Height 10 Cm Are Required to Build a Wall of Length 6 M, Height 2.5 M and Breadth 0.5 M? - Mathematics

Sum

How many bricks of length 25 cm, breadth 15 cm and height 10 cm are required to build a wall of length 6 m, height 2.5 m and breadth 0.5 m?

#### Solution

Let the number of bricks required be n.

Volume of each brick = 25 xx 15 xx 10 = 3750 cm³

Volume of the wall = 6 xx 2.5 xx 0,5 = 7.5 m³

Number of bricks required(n) =  "Vol of wall"/"vol of brick" = 7.5 xx 1000000/3750 = 2000

Thus, 2000 bricks are required to make the wall.
