Test: Cubes - 1 - Class 8 MCQ

A cube has 8 vertices, which are the points where the edges meet.

A cube has 12 edges. Each face of the cube has four edges, and there are six faces in total.

When a cube is cut into smaller cubes, the smaller cubes at the corners will have exactly one face painted.

In a 3 x 3 x 3 cube made up of 27 smaller cubes, the eight smaller cubes at the corners will have at least two faces painted.

The sum of the interior angles of any polygon can be calculated using the formula (n - 2) * 180 degrees, where n is the number of sides. In the case of a cube, it has 6 sides, so the sum of its interior angles is (6 - 2) * 180 = 4 * 180 = 720 degrees.

When a cube is cut into smaller cubes, the cubes at the edges (excluding the corners) will have exactly two faces painted.

When a cube is sliced horizontally into three equal parts, the middle slice will have two painted faces.

The smaller cubes that lie in the interior of the larger cube will have no faces painted.

The volume of a cube can be calculated by raising the length of its side to the power of 3. In this case, 5 cm * 5 cm * 5 cm = 125 cm³.

A cube has six square faces, and a square is the only 2D shape among the options that can be unfolded to form a cube.
