Q1. What is the number of edges in a 10x10 cube?
Ans. 
A 10x10 cube has 600 edges.
• A cube has 12 edges, so a 10x10 cube would have 12 edges on each of its 6 faces.

• 12 edges x 6 faces = 72 edges for the entire cube.

• However, each edge is shared by two faces, so we need to divide by 2 to get the total number of unique edges.

• 72 edges / 2 = 36 unique edges on the outer surface of the cube.

• Since the cube has 10x10x10 = 1000 unit cubes, each with 12 edges, we need to subtract the e...read more
