Summary:

• Area and volume both increase with size but at different rates with volume increasing faster.
• Weight goes as volume while strength (bone and muscle) goes as area.
• Large animals have proportionally thicker bones and stand straighter to support their weight.
• The larger the object the more it tends to sag proportionally under its own weight.
• The larger the object the longer it takes for it to burn or to dissolve.

Optional: The relation between area and volume discussed in this tutorial is sometimes called the "Square-Cube Law"; learn more in this Wikipedia article.
