2. The dice is an example of a cube.
3. A cylinder has 2 flat faces.
4. A solid having ______ surface rolls.
5. A cuboid has 12 edges.
Answer (1)
Let's fill in the blanks step by step for a better understanding of the shapes involved:
A sphere has no corners.
A sphere is a perfectly round 3D shape, similar to a ball. It has a smooth surface without any edges, vertices, or corners.
The dice is an example of a cube.
A standard die (singular of dice) is a cube. A cube is a 3D shape with six equal square faces. Each face is a perfect square, and all angles are right angles.
A cylinder has 2 flat faces.
A cylinder has two flat circular faces, one on the top and one on the bottom, with a curved surface connecting them.
A solid having a curved surface rolls.
A shape with a curved surface, like a sphere or cylinder, can roll. This contrasts with shapes with flat surfaces, like cubes or cuboids, which do not roll smoothly.
A cuboid has 12 edges.
A cuboid is a 3D shape with six rectangular faces. It has 8 vertices and 12 edges. Each opposite pair of faces is identical in shape and size.
