Please find the least area of sheet metal needed to make a water tank.?

A tank is to be made of sheet metal. It is to have a square base and be open at the top. what is the least area of metal that can be used if the tank is to have a volume of 32m^2





please help (with workings) thank you!!Please find the least area of sheet metal needed to make a water tank.?
You can't have a volume of 32m^2. Do you mean 32m^3?





Let l be the length of the sides of the square base of the tank,


h be the height,


and A be the total area of metal used.





Now volume = l * l * h = 32m鲁, so h = 32 / (l * l)


and A = l * l + 4 * (l * h)





Plot a graph of l (= length of base) against A (= total area of metal used) and find the minimum. Or, knowing that the slope of a curve is zero at a minimum or maximum, differentiate A with respect to l, and find a sensible value of l where dA/dl = 0.Please find the least area of sheet metal needed to make a water tank.?
or you can cheat and use excel, and get 48m^2 to be the minimum area. That means base length of 4m and height of 2m

How to calculate sheet metal development size?

i am making a one of the hollow cylinder with using a ss sheet thickness of 2mm. the cylinder inside diameter size is 50mm and outside diameter is 54mm. so how to calculate sheet metal development size and formula. plz help me


thanking uHow to calculate sheet metal development size?
Pie X Dia.= circumference ie 3.14x54=170mm is the width of the sheet reqd.You have not given the length of the cylinder,multiply that length with circumference will give you the area of the reqd.sheet.I do not understand what do u mean by development size.

Is it OK not to use the I/O panel (the thin metal sheet with holes in it) when building a new computer?

I bought a used motherboard and the I/O panel was apparently for a different motherboard. The holes didn't match the motherboard connector jacks (keyboard, mouse, USB ports, sound, etc). I don't see a reason why I can't just skip it, but I might be missing something.Is it OK not to use the I/O panel (the thin metal sheet with holes in it) when building a new computer?
Nope it's not important. Same thing happened to me with a Foxconn mobo.Is it OK not to use the I/O panel (the thin metal sheet with holes in it) when building a new computer?
not really needed.
The panel is pretty much just to keep dust out and sometimes provides info on what each port is for. Unless you'll be using it in a particularly dusty environment, I wouldn't worry about leaving the panel off, as it doesn't ';connect'; to the motherboard or anything. It's just a hunk of metal. :)

  • My father is trying to sell his sheet metal company in Alaska. Where is the best place to advertise for this?

    Do not advertise the company is for sale. His competitors will use the information to their benefit and his harm, plus as soon as you list the business, the value goes down.





    Seek a qualified advisor to help you effectively and confidentially market the business for its maximum value.





    Good Luck.
