Question:

can anyone answer my add math project?differentiation?

the top and bottom pieces of the tin of height h cm are cut from square-shaped aluminium sheets.determine the value for r,and hence calculate the ratio h/r so that the total area of aluminium sheets used for making the tin is minimum.lt;refer to ur own diagramgt;

Answer:

the answer of all baking soda, white vinegar, hydrogen peroxide with some aluminium foil might want to do not have any outcome on metallic with zinc alloy coating,because the pronounced elements will react with one yet another and ensuing answer is only no longer okay to attack metallic.
I'm assuming: The box has a square top and bottomThe volume v is fixedr is the length of a side of the toph is the height of the boxv r^2h h v/r^2 The surface area is a top and bottom both r x r and the sides which are r x hArea 2r^2 + 4rh 2^r^2 + 4r(v/r^2) 2r^2 +4v/r dA/dr 4r -4v/r^2 Set to 0 and solve 0 4r -4v/r^2 0 4r^3 -4v 0 r^3 - v v r^3, or r v^(1/3) That means that the container is a cube.
