Kelsey correctly used the Fermi process and the following estimates to determine how many books would fill a railroad car.

A book is about 1 ft long, 12 ft wide, and 15 ft thick.

A railroad car is about 60 ft long, 10 ft wide, and 10 ft high.

Which equation could she have written?

6*1031*10-1=6*104

6*1031*10-1=6*102

6*1041*10-1=6*105

6*1041*10-1=6*103
