Read each question carefully and determine the shape of the cross section. Draw the cross section if requested and label its dimensions.
1. A cube is sliced by a plane parallel to its base. What shape is the cross section?
2. A right circular cylinder is sliced by a plane perpendicular to its base, passing through the center. What shape is the cross section?
3. A cone is sliced by a plane parallel to its base. What shape is the cross section?
4. Consider a rectangular prism with length 6 cm, width 4 cm, and height 3 cm. Draw the cross section formed by a plane cutting the prism horizontally, parallel to the base.
5. A sphere with a radius of 5 cm is cut by a plane passing through its center. Draw the cross section and label its key dimension.
