1/6 Today, we got the problem. We needed to create a scale factor. We knew that the real bridge had to be 300 ft but it had to be converted into the metric system. It became 91.44 m but we rounded to 93. The scale factor is 1cm=1.5m. The model scale's length will be 62 cm. On graph paper 1block=2cm. The width of the real bridge is 20m and the model bridge is 13.3cm. There are 4 lanes for cars that equal 4 m and 2 lanes for people/bikes that equal 2m. The height of the real bridge is 10 m and the model is 6.6 cm but we rounded it up to 7cm.
