Detailed explanation-1: -A square cross section can be created by slicing the cube by a plane parallel to one of its sides.
Detailed explanation-2: -Cross section of a cube is a square. Since a cube has its faces shaped in square and all the edges of the cube are equal in length. Therefore, when we cut the cube by a plane, we get a square shape.
Detailed explanation-3: -You could also take a slice parallel to the base. Cross sections parallel to the base will be hexagons.
Detailed explanation-4: -Choose a positive length d that does not exceed the side length of the cube and then choose a vertex of the cube. On each of the three edges that share this vertex, mark the point that is a distance d from it. A plane slicing the cube through these three marked points will pro-duce an equilateral triangle.
Detailed explanation-5: -It is also possible to make trapezoid and triangle cross sections that are parallel; the cross section shape will change from a trapezoid to a triangle when the slice intersects the apex. A slice that is parallel to the base will reveal a cross section that is a square or rectangle.
