The height of a pop can is 15 cm and its shadow is 20 cm long. A carton of milk next to the can is 0.25 m tall. Determine the length of the carton's shadow, to one tenth of a centimeter.

Question

I did 100cm*0.25... but the answer is 33.3cm How did they get that?

Answer 1

0.15/20 = 0.25/x

Cross multiply and solve for x.

20 * 0.25 = 0.15x

5/0.15 = x

33.33 = x
