Analysis of a cube</h3>
Let be a cube whose <em>side</em> length is and lines and intersects the cube, then we have a <em>cross</em> section formed by points A, C, E, H. Since , , and , then by 45-90-45 right triangle.
In addition, we know that , and . Hence, we conclude that the cross-section is a rectangle. Hence, the area of the <em>cross-section</em> area is:
(2)
If we know that , then the area of the cross-section is:
The shape of the cross-section is a rectangle and the area of the cross section is square units.
