5. #### 5678

how did you get 247

6. #### 5678

a and b for the last one?

7. #### Miafinucane

I got 30...!! Oops must of got that one wrong hahahah

8. #### kevin quinn

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

9. #### Jakub-j

i got 30 for the tiles

10. #### lolaislola

oh right i get it guess its 47 anyway i dont where i got 200 from

11. #### Roberto Mane

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

You then divide this by 120 to get 3000tiles

12. #### Theo_romo9

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

13. #### Theo_romo9

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

15. #### Cathy20155

I did the same as you @theo_romo9

16. #### Theo_romo9

Sure we'll be fine anyway : ) Good luck anyway
