The main swimming pool has a bottom paved with square tiles with a side of 15 cm. How many tiles lie at the bottom of the pool? (pool dimensions are 50m long and 25m wide. Water depth 1.6m)

Correct answer:

n =  55611

Step-by-step explanation:

a=50 m b=25 cm c=1.6 m d=15 cm m=15:100  m=0.15 m  n1=[a/d]=[50/0.15]=333 n2=[b/d]=[25/0.15]=167  n=n1 n2=333 167=55611
