Answer: The real tree house door should be 126 cm tall.
Explanation:
Given: Two students make a model of a tree house they want to build. The scale is 1:42.
i.e. 1 cm of model = 42 cm in real
if the in the scale model,the door is 3 cm tall, then the height of real tree house door = 3 x (42) cm
⇒ Height of real tree house door= 126 cm
Hence, the real tree house door should be 126 cm tall.
<span>The equator is 0 degree latitude. This imaginary line, which runs through parts of South America, Africa, and Asia, is officially the halfway point between the North Pole and the South Pole.</span>
<span>The prime meridian is 0 degrees longitude. This imaginary line runs through the United Kingdom, France, Spain, western Africa, and Antarctica.</span>
By using the equator and prime meridian, we can divide the world into four hemispheres, north, south, east, and west. For instance, the United States is in the Western Hemisphere (because it is west of the prime meridian) and also in the Northern Hemisphere (because it is north of the equator).
<span>These lines are merely for the identification of where things are on a map or a globe.</span>
A reef than surrounds a volcanic island is an : Atoll
Atoll usually takes shapes in a form of ring that surround the areas of volcanic island that consist of corals. It usually only exist in warm waters, so volcanic islands will provide perfect environment for the corals
