I have questions similar to these and i need help If you can.

[PTT!]

Thank you for your help! I reworded this so it is not my homework but similar and if i could get you help to understand it soon i would be most grateful! Thanks!

General Info
Common aquarium holds 10 gallons. I know volume of a right rectangular tank is found by multiplying the length of the tank times the width times the height, or V=lwh. I know 231 cubic inches are equal to 1 gallon.

The questions

1. A new customer would like an aquarium that is 22 inches long 21 inches deep and holds 16 gallons of water. He wants to know if the tank would fit on a shelf that is 10 inches wide. I need to know if it would fit and why (or why not) I am not good with dimensions.
2. You best customer wonder if you can build her an aquarium with a square bottom that will hold 20 gallons of water. Suggest at least two possible dimensions for the tank (to the nearest tenth of an inch) for her to choose from.
3. A customer wants an aquarium that is exactly twice as long as it is wide and holds 30 gallons of water . Suggest at least two sets of dimensions to the nearest tenth inch that would work for this combination.

Thank you for your time!

   Assume that the width is = W inch
   
   Then the Volume of the tank is = 22 * 21 * W
   
   16 gallons = 16 * 231
   
   Then 22 * 21 * W = 16 * 231
   
   Solve for 'W' and decide...
