There are 6 colors, so 6^3 = 216 different cubes can be obtained.
The cube has 6 faces, each of which can be one of 6 colors.
Therefore, there are 6 options for the first face, 6 for the second, and 6 for the third.
To find the total number of possible cubes, we multiply these options together: 6 x 6 x 6 = 216.
Median is best because it is not affected by outliers and gives a better representation of central tendency.
Median is the middle value in a dataset, which makes it less affected by extreme values or outliers.
It gives a better representation of central tendency as compared to mean, which can be skewed by outliers.
Mode is not always useful as it may not exist or may not be unique in a dataset.
For example, in a dataset of...

Tree traversals are methods of visiting all nodes in a tree data structure.
There are three types of tree traversals: in-order, pre-order, and post-order.
In-order traversal visits the left subtree, then the root, then the right subtree.
Pre-order traversal visits the root, then the left subtree, then the right subtree.
Post-order traversal visits the left subtree, then the right subtree, then the root.
Tree traversals are ...
Pre-order and post-order are traversal methods used in binary trees.
Pre-order: visit root, left subtree, right subtree
Post-order: visit left subtree, right subtree, root
Used to traverse binary trees and perform operations on nodes
Example: Pre-order traversal of binary tree: A, B, D, E, C, F, G
Example: Post-order traversal of binary tree: D, E, B, F, G, C, A
