Problem

The corners or points on a 3D shape are called___

Step

The given image is a cube.

Step

A cube has six faces, each of which is a square. Each face has four edges, and there are a total of 12 edges in a cube.

Step

The edges meet at eight points, which are the vertices of the cube.

Step

So, it is called vertex.

SumUp

Can you summarize what you’ve understood in the above steps?

Choice.A

This is not correct in this context because edges are the line segments connecting vertices, not the vertices themselves. Edges are one-dimensional and represent the boundaries between faces

Edges

Choice.B

Faces are the flat surfaces of the 3D shape. They are enclosed by edges and vertices

Face

Choice.C

This is correct because it accurately describes the corners or points on a 3D shape

Vertices

Choice.D

This is a term commonly associated with 2D shapes, particularly when referring to the line segments that form the boundaries of a shape
