4. anonymous

@Vocaloid

5. Vocaloid

sure

6. anonymous

So for step 1 this is what i put... Width = 2 inches Height = 12 inches Length = 8 inches

7. Vocaloid

right, next step?

8. anonymous

ok

9. anonymous

um for step 2 , i dont get it

10. anonymous

do you remember what the answer was?

11. Vocaloid

a rectangle

12. anonymous

thats the answer for step 2?

13. Vocaloid

yes

14. anonymous

ok let me type it

15. anonymous

ok now step 3

16. anonymous

the surface of the area is: 2*W*H + 2*L*W + 2*H*L

17. anonymous

correct for step 3?

18. Vocaloid

you need to plug in height, width, and length

19. Vocaloid

W = 2 inches H = 12 inches L = 8 inches 2*W*H + 2*L*W + 2*H*L = ?

20. anonymous

um, 272

21. Vocaloid

right, so your surface area is 272

22. anonymous

ok so whats the complete answer for step 3

23. Vocaloid

24. anonymous

its asking for the surface area of the box which is 272

25. Vocaloid

right

26. anonymous

ok now step 4?

27. Vocaloid

sure

28. anonymous

What is the surface area of the box if it is scaled up by a factor of 10?

29. Vocaloid

we've done this before, remember? you multiply each dimension by 10, then you find the new surface area...

30. Vocaloid

31. anonymous

ok so, w=20 H= 120 L= 80

32. anonymous

@Vocaloid

33. anonymous

its you again!

34. Vocaloid

great, now find the surface area

35. Vocaloid

2*W*H + 2*L*W + 2*H*L = ?

36. anonymous

27,200

37. Vocaloid

right

38. anonymous

is that the answer for step 4

39. Vocaloid

yes

40. anonymous

ok now step 5

41. anonymous

What is the volume of the box?

42. Vocaloid

use the dimensions from step 1 and find the volume

43. anonymous

how do i do that?

44. Vocaloid

Width = 2 inches Height = 12 inches Length = 8 inches volume = ?

45. anonymous

192

46. Vocaloid

right...

47. anonymous

ok now step 6

48. anonymous

What is the volume of the box if it is scaled down by a factor of 1/10?

49. Vocaloid

ok, so find the volume...

50. anonymous

um, W=0.2 H= 1.2 L=0.8

51. Vocaloid

great, now find the volume...

52. anonymous

how?

53. Vocaloid

volume = w*h*l

54. anonymous

0.192

55. Vocaloid

right

56. anonymous

thats it!

57. anonymous

thank you so much! your a great help and super smart :) You definitely deserve a medal!! :)

58. anonymous

$2\div10$

59. anonymous

$\frac{ 1 }{ 10 }$

60. anonymous

yup 1/10 is right Iv'e been watching the whole convo
