For a school project, Sarah plans to build a scale model of an Egyptian pyramid. She will be using a scale of: 1 cm = 4 meters.
If the pyramid is 140 meters tall, how tall will her model pyramid be?
To find the height of the model pyramid, we can set up a proportion:
Model height / Actual height = Scale factor
Let x be the height of the model pyramid.
x / 140 = 1 / 4
Cross multiply to solve for x:
4x = 140
x = 140 / 4
x = 35
Therefore, the model pyramid will be 35 cm tall.
