Therefore, the equation of the line is
<em>The dimensions of the cardboard to make a box without a lid is 11 inches by 11 inches.</em>
<h2>Explanation:</h2>In this problem, we have that Isabelle is using a square piece of cardboard to make a box without a lid. She cuts 2-inch squares from each corner and folds up the edges. The figure below shows this statement. The finished box has a volume (V) of 98 cubic inches, in other words:
When folding up, we get the box without lip shown in the second figure. So the volume would be:
Since te cardboard is square, then the side (s) is given by:
Therefore:
