V=l*w*h
48=2*3*8
A=2(l*w+l*h+w*h)=2(2*3+2*6+3*8)=2(6+12+24)=2*42=84
48=4*4*3
A=2(4*4+4*3+4*3)=2(16+12+12)=2*30=60
48=2*4*6
A=2(2*4+2*6+4*6)=2(8+12+24)=2*44=88

Essentially you have your answer so you need to come up with 3 questions when multiplied you will get the answer 48
48 x1 x1= 48 a very long and skinny box for a rose perhaps :-) Area is tehrefore length x width 48x1 = 48 square units
12 x 2 x 2 = 48 Area = 12 x 2 = 24 square units
see if you can work out the third :-)

Volume is length times witdth times height. So pick 2 of these numbers and then find out what the third has to be for them to multiply to get 48. For example
1 unit by 1 unit by 48 units is one set of measurements. Then you need to compute the surface area which is the sum of the area of each of the six sides. Good luck.

You know, I click on your handle to look at your recent questions. It looks to me like you're just wanting someone to do your homework. That will work in the short term but it will limit the types of careers that you find available to you.
