if a can made out a thin sheet of tin , which cost about 0.25$ per square meter . my question is for various height to diameter ratio ( H/D ) values and several can volumes (V), what is the equation used to calculate the cost ?
what is my equation to calculate cost ?
answer : if h/d=x then h=x*d.....1
volume of cylinder = pi*r^2*h= pi*r^2*xd ,where r=d/2
if volume is given then
d=(v*4/(pi*x))^1/3......2
then surface area =(2*pi*r^2)+2*pirh......3
substitute with 1 and 2 in 3 and then multiply them with the cost value for meter square.
