Mr. behera wants to build a house for his wife. In this there are 5 rooms each having equal area. The length of each room is 4m,, breadth is 5m. The height of the rooms is 2m. If to make a sq meter we need 17 bricks, then how many bricks are needed to make the floor of a particular room?

• 340
  
  Area of floor of room = 4*5=20 sq mtr.
  
  If to make a sq meter we need 17 bricks, then 20*17=340 bricks are needed to make the floor of a particular room.

• area of 4 walls of a room= 2*(lenth+breadth)*height.
  that formula will be used
  ans is 2*(4+5)*2=20
  for 5 rooms=20*5=100
  then no of bricks r required=100*17=1700
