<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:
![V=98in^3](https://tex.z-dn.net/?f=V%3D98in%5E3)
When folding up, we get the box without lip shown in the second figure. So the volume would be:
![V=2xx \\ \\ V=2x^2 \\ \\ But: \\ \\ V=98 \\ \\ Then: \\ \\ 2x^2=98 \\ \\ x^2=49 \\ \\ x=\sqrt{49} \\ \\ x=7in](https://tex.z-dn.net/?f=V%3D2xx%20%5C%5C%20%5C%5C%20V%3D2x%5E2%20%5C%5C%20%5C%5C%20But%3A%20%5C%5C%20%5C%5C%20V%3D98%20%5C%5C%20%5C%5C%20Then%3A%20%5C%5C%20%5C%5C%202x%5E2%3D98%20%5C%5C%20%5C%5C%20x%5E2%3D49%20%5C%5C%20%5C%5C%20x%3D%5Csqrt%7B49%7D%20%5C%5C%20%5C%5C%20x%3D7in)
Since te cardboard is square, then the side (s) is given by:
![s=2+x+2 \\ \\ s=2+7+2 \\ \\ s=11in](https://tex.z-dn.net/?f=s%3D2%2Bx%2B2%20%5C%5C%20%5C%5C%20s%3D2%2B7%2B2%20%5C%5C%20%5C%5C%20s%3D11in)
Therefore:
<em>The dimensions of the cardboard to make a box without a lid is 11 inches by 11 inches.</em>
