The diagram shown is a cube. If a plane slices horizontally through the solid, what is the shape of the cross-section? A) kite B) oval C) square D) trapezoid

If a "plane slices horizontally" through a solid cube, the shape of the "cross-section" would be a square.

Explanation:

A solid cube is a block with six distinct faces. Every vertex angle of a cube is exactly 90°. If the cube is placed on one of its horizontal faces and is sliced horizontally keeping the cut parallel to its horizontal face, the sliced cube would get the shape of a square ("if viewed from the top").

Answer: C) Square

Explanation:

A cube is a three dimensional square. If you cut one in half it will be a square.
