What is cube and examples?

• Common examples of Cube in real life are square ice cubes, dice, sugar cubes, Rubik's cube etc.
• A cube shape is like that of perfect square.
• Cube is a three-dimensional box-like figure represented in the three-dimensional plane. Cube has \(6\) square-shaped equal faces.

How many sides is a cube?

• In geometry, a cube is a three-dimensional solid object bounded by six square faces, facets or sides, with three meeting at each vertex.

How many corners does cube have?

• The sides of each face are called edges. A cube has 12 edges.

According to the question:

In this particular cube 4  sides are painted and 2 are not painted.

Therefore, these 4 sides have cubes with 2 faces painted.

Now, the cubes with 2 faces painted are the cubes on the sides except the corner ones.There are 8 cubes for 2 painted faces.

Hence, there will be total of 16 cubes with 2 painted faces.
