A box with no top is made by taking a rectangular sheet of metal and cutting away four equalsized squares (one from
each corner of the sheet) and then folding up the resulting
aps. The box should be made 4 cm deep and the length of the
base should be 15 cm more than the width. If the volume is to be 1000 then what should be the width of the sheet of metal?

Best ResponseYou've already chosen the best response.0ok so volume here is 1000. 1000=length*width*height, say width=x then length=x+15. so solve the quadratic equation 4x^2+20x1000=0

Best ResponseYou've already chosen the best response.0oh i forgot about the boxes that were cut out, yes 10 is the width of the inner box but its made from the sheet metal so you have to add the little boxes you cut off which makes it 10+4+4=18, however my reasoning was correct to get 10. i just failed to realize that thats not what the question asked for.
