An open box is to be made from a flat square piece of material 18 inches in length and width by cutting equal squares of length from the corners and folding up the sides.
Write the volume of the box as a function of x. Leave it as a product of factors; you do not have to multiply out the factors.
If we write the domain of the box as an open interval in the form (a,b) , then what is a? b?
please help me. it have til 4:00 pm
Dash in lines for where you'll be folding up the sides.
Using the given dimension and the given variable, create an expression for the dimensions of the base of the box, given that you'll be folding up a width of "x" units on each side.
Obviously the height of the box is "x". What expressions represent the other two dimensions? Multiply the variable and the expressions to find the volume V in terms of the variable.
