A great example of a physical boundary is a mountain. For example, the Pyrenees Mountains, which serve to separate France and Spain, are a physical boundary. So are the Ural Mountains which separate Europe and Asia. Along with mountains, oceans, seas, even deserts are examples of physical boundaries.
An average size apple weighs 6.4 ounces, which is equal to 180  grams. One apple contains approximately 91 calories and 3 grams of  dietary fiber.
How many apples makes up 1.5 kilograms if each weigh 225 grams? 1.5 kilograms is equal to 1500 grams and 1500 divided by 225 equals 6.667 so a little over six and a half apples makes up 1.5 kg or rounding up it would be 7 apples.
