A box with an open top is to be constructed from a rectangular piece of cardboard with dimensions 18 in. by 30 in. by cutting out equal squares of side x at each corner and then folding up the sides as shown in the figure. Express the volume V of the box as a function of x.A rectangular shaped object is shown. The longer sides are horizontal and labeled with a length of 30. The shorter sides are vertical and labeled with a length of 18. The rectangle is shaded green except for 4 white squares. One square is located at each of the four corners of the rectangle and each square has side length labeled x. A second image is also included of what the box will look like after the corners are removed. It has a rectangular bottom, 4 folded up sides, and no top. An unlabeled box with an open top is shown.V(x) =

Consider the following problem: A box with an open top is to be constructed from a square piece of cardboard, 3 ft wide, by cutting out a square from each of the four corners and bending up the sides. Find the largest volume that such a box can have.(a) Draw several diagrams to illustrate the situation, some short boxes with large bases and some tall boxes with small bases. Find the volumes of several such boxes.(b) Draw a diagram illustrating the general situation. Let x denote the length of the side of the square being cut out. Let y denote the length of the base.(c) Write an expression for the volume V in terms of both x and y.V = x(3−2x)(3−2x) (d) Use the given information to write an equation that relates the variables x and y.y=3−2x (e) Use part (d) to write the volume as a function of only x.V(x) = x(3−2x)(3−2x) (f) Finish solving the problem by finding the largest volume that such a box can have.V = ft3

A rectangular piece of cardboard twice as long as it is wide is to be made into an open box by cutting 2-cm squares from each corner and bending up the sides. Express the volume V of the box as a function of the width w of the piece of cardboard.V(w) = 4w^2 - 24w + 32V(w) = 3w^2 + 12w + 23V(w) = 2w^2 - 24w + 20V(w) = w^2 - 50w + 11

an open box is to be made from a 15ft by 40ft rectangular piece of sheet metal by cutting out squares of equal size from the four corners and bending up the sides. Find the maximum volume that the box can have round answer to nearest integer the maximum volume is blank ft^3

A paper sheet is of rectangular shape of 24 cm by 13 cm from each of its corners a square of 4 cm is cut off. An open box is made of the remaining sheet, what is the volume of the box.
