Which one of the following groups have all 3-dimensional shapes?

Correct Answer: Cube, Cuboid, Sphere, Cylinder

Explanation:

To determine which group contains only 3-dimensional (3D) shapes, let's understand the difference between 2-dimensional (2D) and 3-dimensional (3D) shapes:

1. Two-Dimensional (2D) Shapes: These are flat shapes that have only two dimensions—length and width (or height). They do not have depth or thickness. Examples include circles, triangles, squares, and semi-circles.

2. Three-Dimensional (3D) Shapes: These are solid figures or objects that have three dimensions—length, width, and height (or depth). They occupy space. Examples include cubes, cuboids, spheres, cylinders, and cones.

Now, let's evaluate each option:

• Cube, Cuboid, Semi-circle, Cone: Semi-circle is a 2D shape, so this group does not contain all 3D shapes.

• Cube, Cuboid, Circle, Cone: Circle is a 2D shape, so this group does not contain all 3D shapes.

• Cube, Cuboid, Circle, Triangle: Both Circle and Triangle are 2D shapes.

• Cube, Cuboid, Sphere, Cylinder: All four shapes (Cube, Cuboid, Sphere, and Cylinder) are 3-dimensional (3D) solid shapes.

Therefore, the group containing all 3-dimensional shapes is Cube, Cuboid, Sphere, Cylinder.
