Question 1160190: An open-­‐topped storage box is to be made from a sheet of cardboard 8 feet by 10 feet. The sides of the box are formed when a congruent square is cut from each corner, which allows the sides to fold up. The base of the box has an area of 28.16 sq. feet.
Write an equation to represent the area of dimensions of the base.
Determine the side length of the congruent squares.
Determine the dimensions of the box

x, side length of the congruent squares

%288-2x%29%2810-2x%29=28.16

simplification
2%2A2%284-x%29%285-x%29=28.16
%284-x%29%285-x%29=7.04
