Arectangular sheet of cooper is twice as long as it is wide. from each corner a 3-inch square is cut out, and the ends are then turned up to form a tray. if the volume of the tray is 324 cubic inches , what were the original dimensions of the sheet of cooper?

length=24 inches and width=12 inches

Step-by-step explanation:

Let width of the rectangular sheet be x.

Then its length is twice as width = 2x

From each corner 3-inch square is cut to form a tray.

The length of the tray formed = l = 2x-6 (total length - length of 2 squares cut out from both ends)

The width of the tray formed  = b = x-6 (total width - length of 2 squares cut out from both ends)

Height of the tray formed = h = 3 inches

Volume of the tray = l*b*h = (2x-6)*(x-6)*3 = 324 cubic inches.

The length and width of the sheet is 24 and 12 inches respectively.

24+x=y

step-by-step explanation:

i get you, what you should do is think of the positive things that would come out of it. it will make yours parents proud and raise your grade. you should always try and if you can't focus tell the teacher.
