Question 209904: Hi this is Domonique again. Thank you for your help last time. I am having a problem with the same question. I had to take a object and get its volume and surface area. I chose a mini Kit Kat bar. The lenght is 8cm, width is 1cm, and height is 3cm. The volume I got was 24, the surface area was 70. I am puzzled now. I have to enlarge this object surface area and volume by a 1:6 ratio. I am very lost. I really tried and don't understand how to do this.Please help me. And what do I write behind each one. Is it cubic meter or square feet.
Thank you in advance.

take a object and get its volume and surface area. I chose a mini Kit Kat bar.
The lenghth is 8cm, width is 1cm, and height is 3cm.
The volume I got was 24, the surface area was 70.
:
That seems right:
:
I have to enlarge this object surface area and volume by a 1:6 ratio
:
Surface area enlarged 1:6
Let x = enlarged surface area
70%2Fx = 1%2F6
x = 70*6
x = 420 sq/cm
:
Volume enlarged 1:6
24%2Fx = 1%2F6
x = 24*6
x = 144 cu/cm
;
If you need to find the dimensions of the enlarged object:
multiply each of the original dimensions by cube root of 6 for the increased volume
and
multiply each of the original dimensions by the sqrt%286%29 to get the increased surface area
