## anonymous one year ago 1.List the dimensions of your box. Be sure to include the units (in, cm, ft, etc.). 2.Describe the shape of the cross section when the box is cut parallel to the base. 3.What is the surface area of the box? 4.What is the surface area of the box if it is scaled up by a factor of 10? 5.What is the volume of the box? 6.What is the volume of the box if it is scaled down by a factor of 1 10 ?

1. AbdullahM

...and you want us to do your assignment for you?

2. misssunshinexxoxo

Where's the box?

3. AbdullahM

More like, where is your work?

4. anonymous

hey i got it

5. AbdullahM

Got what?

6. anonymous

wait a second

7. anonymous

I got my dementions

8. anonymous

i got my box

9. AbdullahM

ok

10. anonymous

its L= 30cm W= 21cm

11. AbdullahM

There has to be another dimension. What is the height?

12. anonymous

30cm

13. anonymous

hey ? would you get you hieght from the base up.

14. anonymous

actualy the box is standing up

15. AbdullahM

|dw:1435412007909:dw|

16. anonymous

ohh

17. anonymous

wait give me a second

18. AbdullahM

|dw:1435412180299:dw| Found a better picture

19. anonymous

ok so my with would be 13

20. anonymous

i just measured it.

21. anonymous

i mean hight

22. AbdullahM

L= 30cm W= 21cm H= 13 cm

23. AbdullahM

Surface Area of a Rectangular Prism = 2LW + 2LH + 2WH

24. AbdullahM

So calculate the Surface Area using the dimensions and that formula I just posted.

25. anonymous

yes i am calculating one second.

26. anonymous

hey is it 2lxw

27. anonymous

it is 68147

28. AbdullahM

How did you get that?

29. anonymous

al i did was did what you told me

30. anonymous

abdullahM

31. anonymous

but i dont get it am i apost to add them up, x and then ad what.

32. anonymous

?

33. AbdullahM

$$\sf\Large (2\times 30\times 21) + (2 \times 13 \times 21) + ( 2\times 13 \times 30)=?$$

34. anonymous

i new it hey ty

35. anonymous

but still not done

36. anonymous

134365920

37. AbdullahM

how are you getting such huge numbers?

38. AbdullahM

ok, lets do this part by part

39. anonymous

ok

40. AbdullahM

what is $$\sf\Large (2\times 30\times 21) =?$$

41. anonymous

1260

42. AbdullahM

ok, now what is: $$\sf\Large (2 \times 13 \times 21)=?$$

43. anonymous

546

44. AbdullahM

and finally what is $$\sf\Large ( 2\times 13 \times 30)=?$$

45. anonymous

780

46. AbdullahM

and now finally what is: $$\sf\Large 1260 +546 +780=?$$

47. anonymous

2586

48. AbdullahM

49. anonymous

ok ty

50. AbdullahM

|dw:1435414080138:dw|

51. AbdullahM

erm let me fix that picture, brb

52. AbdullahM

|dw:1435414559024:dw|

53. AbdullahM

there we go

54. AbdullahM

so what would be the cross section?

55. AbdullahM

hello....

56. anonymous

it is square AbdullahM

57. anonymous

excuse me but can i gett alittle bit of assistance please.

58. anonymous

xapproachesinfinity

59. anonymous

so u r going 2 sit ther and wait, for what?

60. AbdullahM

well in the example it is a square, but for your question it would have to be a rectangle.

61. anonymous

ok ty

62. AbdullahM

for #4, multiply the surface area (2586) by 10

63. anonymous

it is 25860

64. anonymous

ok

65. anonymous

AbdullahM

66. AbdullahM

correct

67. AbdullahM

what is the formula for calculating volume? it's an easy formula :)

68. AbdullahM

yohooo, I don't got all day...

69. anonymous

hey bro i am sorry my computer is kicking mmy butt and i had to walk my dogs.

70. anonymous

AbdullahM

71. AbdullahM

btw, you tag people like @Tootles143 you should kinda already know that..

72. anonymous

dood i am in 7th grade and i am in virtual school i dont understand the math with out it being taught to me. and this is not my openstudy it is my sisters this is her accout just using it for help.

73. anonymous

The volume of a rectangular prism is the length on the side times the width times the height.

74. AbdullahM

so what is the volume for this box?

75. AbdullahM

$$\color{blue}{\text{Originally Posted by}}$$ @AbdullahM L= 30cm W= 21cm H= 13 cm $$\color{blue}{\text{End of Quote}}$$

76. anonymous

abc

77. anonymous

is t like in that form

78. AbdullahM

yes

79. anonymous

ok

80. anonymous

ok so 30x21x13

81. AbdullahM

and that is..

82. anonymous

8190

83. anonymous

abdullah

84. AbdullahM

85. AbdullahM

86. anonymous

is it 819
