Find the volume, total surface area, lateral surface area and the length of diagonal of a cube, each of whose edges measured `20 cm`

Explanation

To solve the problem of finding the volume, total surface area, lateral surface area, and the length of the diagonal of a cube with edge length of 20 cm, we can follow these steps:

### Step 1: Calculate the Volume of the Cube
The formula for the volume \( V \) of a cube is given by:
\[ V = A^3 \]
where \( A \) is the length of an edge of the cube.
