Explanation:
a) A triangle has 3 sides and 4 vertices:
This statement is incorrect. A triangle is a polygon with three sides and three vertices. The sum of the interior angles of a triangle is always 180 degrees.
b) A cylinder has 3 faces:
This statement is incorrect. A cylinder has two circular faces and one curved surface. Therefore, a cylinder has three surfaces, not three faces. The two circular faces are the top and bottom of the cylinder, and the curved surface wraps around the sides.
c) All sides of the rectangle are equal:
This statement is incorrect. A rectangle is a quadrilateral with four right angles, but the opposite sides of a rectangle are equal in length, not all sides. The opposite sides of a rectangle are parallel and equal in length, while the adjacent sides are perpendicular to each other.
d) A cuboid has 4 flat faces and 12 straight edges:
This statement is incorrect. A cuboid is a three-dimensional shape with six rectangular faces. It has eight vertices, twelve edges, and six faces. All the faces of a cuboid are flat, and all the edges are straight.
Conclusion:
The correct statement from the given options is option 'B' which states that a cylinder has 3 faces.
