Question 593045: I am building a box. I know the area of each side of a rectangular box is 252, 168 and 96. The total surface area is 2(252 +168 + 96)=1,032. How can I find the dimensions of the l,w,and h. Since I know the surface area of each side I came up with the following: l*w=252, l*h=168, w*h=96. Would I start by solving for l as in l=252/w and then substitute it into the next equation as (252/w)h=168. This is when I get confused.

Question 597839: You want to form a rectangular pen of area, a=70 ft^2. One side of the pen is to be formed by an existing building and the other three sides by a fence. If w is the width of the sides of the rectangle perpendicular to the building, then the length of the side parallel to the building is L=70/w. The total amount of fence required is the function F=2w + 70/w, in feet.
Determine the dimensions of the rectangle that requires a minimum amount of fence. Round to decimal places.
width = feet
length = feet
I have been having difficulty with area problems. Any help would be greatly appreciated. Thanks!!!
