For your science class, you have to build a miniature model of the polar bear habitat at the zoo. After talking with the zookeepers, you learn that the habitat is 20 feet long, 15 feet wide and 25 feet high. You are going to design your model so that its linear dimensions are 20 times smaller than the actual habitat. What is the height of your model (in inches)? [12 inches in 1 foot]

Question

Your first step would be to convert the feet to inches; that is, multiply all the dimensions by 12.

okay what about the second step

anonymous · Answer

actually, all you need to worry about is the height. The given height is 25 feet. Convert this to inches. Then, divide by 20 to get the model's height

anonymous · Answer

(dividing [number] by 20 is the same as 20 times smaller than [number])

anonymous · Answer
