4000 pieces of stones needed

Explanation:

All measurements should be taken in cm unit wise

For wall:

  • 20 m = 2000 cm
  • 60 cm = 60 cm
  • 2 m = 200 cm

For each stone:

  • 20 cm
  • 30 cm
  • 10 cm

Volume of the wall:

  • 2000 x 60 x 200
  • 24000000 cm³

Volume of each stone:

  • 20 x 30 x 10
  • 6000 cm³

Pieces of stone needed:

  • 24000000/6000
  • 4000 pieces of stones

Answer:

=> 4000 pieces

Step-by-step explanation:

First change m into cm

20m -> 2000cm

2m -> 200cm

volume of wall = 2000×200×60

=> 24000000 cm³

volume of each stone = 20×30×10

=> 6000 cm³

stone needed = 24000000/6000

=> 4000 pieces
