1. gabbyalicorn

The cube has a surface area of 24 cm2. What would the surface area of the prism be if each dimension were quadrupled?

2. gabbyalicorn

im guessing 24 x 2^¢4

3. gabbyalicorn

24 x 2^4

4. gabbyalicorn

@Black_ninja123

5. Black_ninja123

2*4=8

6. Black_ninja123

8^6

7. Black_ninja123

one sec

8. gabbyalicorn

i thought 2 x 2 x 2 x 2 :/

9. gabbyalicorn

kk

10. Black_ninja123

what is 2^4

11. gabbyalicorn

8

12. Black_ninja123

no not 4*2

13. Black_ninja123

2^4

14. gabbyalicorn

4

15. Black_ninja123

16 because 2*2*2*2

16. gabbyalicorn

oh ur doing 4 x 4

17. Black_ninja123

what is 6*16^2

18. gabbyalicorn

|dw:1433391751274:dw|

19. Black_ninja123

Correct

20. Black_ninja123

21. gabbyalicorn

|dw:1433391865651:dw|

22. Black_ninja123

yes

23. gabbyalicorn

Thank you!!!!

24. Black_ninja123

25. gabbyalicorn

it only lets me type in 3 numbers

26. gabbyalicorn

well i guess that will stil work

27. gabbyalicorn

still*

28. triciaal

hi, just got on quadrupled means 4 times cube 3 dimensions, each the same length

29. gabbyalicorn

so 4 x 4 x4

30. gabbyalicorn

which would be 4096

31. triciaal

surface area of a prism = 2B + Ph where B is the area of the base , P is the perimeter of the base and h is the height

32. gabbyalicorn

eh? 2 x 2 + 4096 ?

33. gabbyalicorn

4,100

34. gabbyalicorn

?

35. gabbyalicorn

36. Black_ninja123

I'm really confused

37. gabbyalicorn

:/

38. gabbyalicorn

So, do we just wait till triaacal come back?

39. Black_ninja123

Yea i guess she has another way to solve it and i guess my way was wrong

40. gabbyalicorn

but i can only put three numbers in the box, i guess it would be 410 of something

41. Black_ninja123

42. gabbyalicorn

no

43. Black_ninja123

the surface area of a cube is SA=6a^2

44. triciaal

@Black_ninja123 and a is 2 and the area was given in the problem 24

45. triciaal

@gabbyalicorn I thought this was done and the medal awarded.

46. gabbyalicorn

I'm still confused about the answer 4100? but then i could only put 3 numbers in the box so then im wondering 410 ?

47. triciaal

@Black_ninja123 what are you confused about?

48. Black_ninja123

The formula you used

49. gabbyalicorn

ugh, i dont know there are two answers but i guess the one that @Black_ninja123 put is wrong "@Black_ninja123 and a is 2 and the area was given in the problem 24"

50. triciaal

the surface area of the prism = 2B + Ph (straight from a textbook) B is the area of the base, P is the perimeter of the base and h is the height the original dimensions of the cube each side 2 units when quadrupled means each side now 4*2

51. gabbyalicorn

so 16?

52. triciaal

|dw:1433393600062:dw|

53. triciaal

no, *means multiply and ^ means exponent

54. gabbyalicorn

im thinking 4 x 4 when you do 4*2.

55. triciaal

yes I see that that's why I showed the different symbols

56. gabbyalicorn

k

57. gabbyalicorn

but 16 isn't the answer? 1400 is?

58. triciaal

my approach is to find the surface area of the prism with side 2 by finding the

59. triciaal

4 * 2 = 8 this is just the new measurement of the side of the cube

60. gabbyalicorn
