mr. m has an 8 inch by 11 inch sheet of paper. He created a box by cutting congruent squares from each corner.The base of his box is 54 square inches.How much did he cut from each corner. (algebraic solutions only)

I'm sorry, but I'm not a math tutor. My skills stop at about 7th grade.

An open box is to be made from a rectangular piece of tin 12 inches long and 10 inches wide by cutting pieces of xinch square from each corner and bending up the sides.
a. Find a formula that expresses the volume V of the box as a function of x.
b. Find the domain of the function.
