      it wasnt a big number like 250 cause the tiles were 20x20 cm so you then had to convert that to metres because the area of the pool was in metres

      for the minimum tiles it was .2x.2=0.04

      You then divide this by 120 to get 3000tiles

      400 cm is equal to 4metres not 0.04 metres.

      120 is not the inside of the pool , that is just 8 x 15 which is just the base. You have to also get the area of the sides

      But 400cm squared is equal to 0.04 metres squared. The area would then be 2 ( 1.4 x 15 ) + 2( 1.4 x 8 ) + 120

      42+22.4+120 = 184.4

      tiles = 184.4 divided by 0.04 = 4610 .

      Im pretty sure I got that right = )

      I dont think they meant for you to count the walls of the pool,but if they did then you're correct and if they didn't then I'm right.Too bad we'll never know
