You have been asked to build a scale model of your school out of toothpicks. Imagine your school is 30 feet tall. Your scale is 1 ft:1.26 cm.
A)If a toothpick is 6.3cm tall, how many toothpicks tall will your model be?
B)Your mother is out of thoothpics, and suggests you use cotton swabs instead. You measure them, and they are 7.6cm tall. How many cotton swabs tall will your model be?
THANK YOU SOOO MUCH!!
A. h = 30Ft * 1.26cm/Ft = 37.8 cm. = Ht. of the model.
37.8cm * 1toothpick/6.3cm = 6 Toothpicks
B. 37.8cm/7.6 =
To find the number of toothpicks tall your model will be, you need to compare the height of your school with the height of a toothpick and their respective scales. Here's how you can calculate it:
A) First, convert the height of your school into centimeters, as the scale is in centimeters. Since there are 30.48 centimeters in a foot, the height of your school in centimeters is:
30 ft × 30.48 cm/ft = 914.4 cm
Next, divide the height of your school by the height of a toothpick:
914.4 cm ÷ 6.3 cm = 145.4 toothpicks
Therefore, your model will be approximately 145.4 toothpicks tall.
B) To determine the height of your model using cotton swabs instead of toothpicks, we need to follow a similar process. The height of a cotton swab is given (7.6 cm) compared to the scale ratio (1 ft:1.26 cm). Here's how to calculate it:
Convert the height of your school into centimeters:
30 ft × 30.48 cm/ft = 914.4 cm
Then, divide the height of your school by the height of a cotton swab:
914.4 cm ÷ 7.6 cm = 120.3 cotton swabs
So, your model would be approximately 120.3 cotton swabs tall.
You're welcome! If you have any more questions, feel free to ask!
