@AriPotta

2. AriPotta

does that box say 225cm^3?

3. userneedinghelp

yes ma'am

4. across

Use the Pythagorean theorem.

5. AriPotta

mmk. so we know it's a square and it has an area of 225. how would we find the side length?

6. userneedinghelp

a2+b2=c2?

7. userneedinghelp

o side length is the square root of the area

8. across

Yes, now identify \(a\), \(b\) and \(c\) and solve for the unknown variable.

9. userneedinghelp

. ill solve n tell u what i got in five mins s, tnx

10. userneedinghelp

will you wait five mins plz?

11. userneedinghelp

u find the sq root of 17 and 225?

12. AriPotta

just find the square root of 225. 17 is the side length of that one square

13. userneedinghelp

oh. alright,.

14. userneedinghelp

tis 15

15. userneedinghelp

the sq root of 17 is about 8.5

16. AriPotta

you don't need the square root of 17

17. userneedinghelp

18. userneedinghelp

oh mk

19. userneedinghelp

so 15+ 17 = c2?

20. AriPotta

a^2 + 15^2 = 17^2

21. userneedinghelp
