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:1.47 cm.
If a toothpick is 6.3 cm tall, how many toothpicks tall will your model be?
1.47cm * (1pick/6.3cm) = 0.233 pick
1 ft : 1.47cm = 1 ft : 0.233 pick = 30 ft : 7 picks
To find out how many toothpicks tall your model will be, you need to first calculate the height of your school in centimeters according to the given scale.
Since the scale is 1 ft:1.47 cm, the height of your school in centimeters will be:
30 ft * 1.47 cm/ft = 44.1 cm
Now, you need to determine how many toothpicks will fit into this height. Since each toothpick is 6.3 cm tall, you can divide the height of your school in centimeters by the height of a toothpick to find the number of toothpicks:
44.1 cm / 6.3 cm/toothpick ≈ 7 toothpicks
Therefore, your scale model of your school will be approximately 7 toothpicks tall.
