Question

How many bricks each of dimensions 10 cm ×8cm× 6 cm will be required to built a wall of dimension 5m ×1.2 m × 2 m ? If the bricks sell at rs 2000 per thousand, find the cost of building the wall ?

Answer 1

volume of brick= 10*8*6= 480cm3
volume of wall =500*120*200=12000000cm3
therefore number of bricks needed =>
12000000/480=25000 bricks
rate of brick = 2000per 1000 bricks
=>rs.2per brick
cost of building the wall = 2*25000
rs. 50000
I hope this will help u

Answer 2

Answer:

Step-by-step explanation:

volume of brick= 10*8*6= 480cm3
