Question

5. A brick measures 2.3 dm by 1.1 dm by 0.8 dm. How many bricks will be required for a wall 92
metres long, 4 metres high and 0.264 metre thick?​

Answer 1

Answer:

480

Step-by-step explanation:

Given: dimensions of brick = 2.3*1.1*0.8

          dimensions of wall   = 92*4*0.264

To Find: no of bricks in the wall

Solution: volume of brick = 2.3*1.1*0.8 = 2.024 dm (20.24 m)

              volume of wall   = 92*4*0.264 = 97.152 m

      Therefore, no of bricks in the wall: 97.152/20.24

                                                                                                 =480
