Cube Geometry and Diagonal Calculations

The video tutorial explains how to calculate the length of a hole drilled diagonally through a cube bead. The instructor visualizes the cube, identifies the longest diagonal, and applies the Pythagorean theorem to find the diagonal's length. The final calculation reveals that the length of the hole is the square root of 3 over 2 centimeters.

What is the length of each edge of the cube bead?

• 1/2 cm

• 1/4 cm

• 1 cm

• 2 cm

What is the longest diagonal in a cube?

• The diagonal of one face
