Adding materials to objects in 3D studio max

The next step was top open up the materials tab by pressing keyboard shortcut "m".
The following is the material tab:

In the materials tab you can select a map by clicking one of the squares in the selection box, the next step is to pick a material by clicking the box next to diffuse. there are some default materials already install so in one i have chosen wood. the others are planet and cellular.
you can then drag and drop the map box onto the object to apply the select material.
In the following picture i have added three seperate maps to three seperate cubes:

This is how i added material.
