A model car is a 1/43 scale model of the original car. What is the scale factor needed to find the dimensions of the original car? model car=4.2" long, 1.3"tall, and 1.6" wide?

  • 8th grade math -

    (1/43)L = 4.2
    L = 4.2 / 0.02326
    L = 180.567 inches = 15.047 feet

    Follow that pattern for the height and width.
