Question

A model of a​ tractor-trailer is shaped like a rectangular prism and has a width of 3 in., a length of 7 in., and a height of 4 in., The scale model is 1: 33. How many times the volume of the model is the volume of the actual​ tractor-trailer?

Answer 1

Volume of the model:
V m = W x L x H = 3 x 7 x 4 = 84 in³
Volume of the actual tractor-trailer:
V t = (3 *33) x (7*33) x (4 * 33) = 84 * 33³ = 84 * 35,973
Answer:
V t = 35,937 V m
