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 5 m. The height of the rooms are 2m. If for making a sq. meter, we need 17 bricks ,then how many bricks are needed to make the floor of particular room?

• area of the floor = length*breadth=4*5=20
  therefore no. of bricks required= 17*20=340
