Question 1199113: The following problem is often used in textbooks using different measures.
An open box is to be constructed from a square piece of sheet metal by removing a square of side 1 foot from each corner and turning up the edges. If the box is to hold 4 cubic feet, what should be the dimensions of the shert metal?
Let me see.
I can label the length of a side of the square piece of metal as x.
The box will be of height 1 foot, and it's square base will measure (x - 2) on each side. The volume V of the box is V = (x - 2)(x - 2) • 1 or (x - 2)^2.
Is this right so far?
