1. The figure above shows a plane intersecting a cube through four of its vertices. An edge length of the cube is 6 inches. a. Describe the shape formed by the cross section. b. What is the perimeter of the cross section? (Hint: the diagonal cuts the square into two right triangles. Use what you know about right triangles to determine the length of the cross section) C. What is the area of the cross section?
