A hall 36m long and 15m broad is to be paved with stones, each measuring 3dm by 5 dm. The number of stones required is:  Choices: A) 3600 B) 1800 C) 18 D) 18000 E) 1.8
3600rea of the hall= 3600*1500   3600rea of each stone= (30*50)   Therefore, number of stones= (3600*1500/ 30*50)= 3600   3600NSWER:3600
