A railway car is in the shape of a rectangular prism. The railway car is 3 m wide, 20 m long and has a height of 2.8 m. determine then volume of the railway car in cubic cm.
okay there is 100 cm in 1 m so 3 x 100= 300, 20 x 100 =2000, 2.8 x 100= 280. I multiplied all of them and I got 168000000 cubic centimeters. Is this right? if wrong I'm I suppose to add all of them instead of multiplying all of them? Thank you

A man is walking his dog on a leash towards home at a steady 4 mph. When they are nine miles from home, the man lets the dog off the leash. The dog immediately runs off towards home at 9 mph. When the dog reaches the house, it turns around and runs back to the man at the same speed. When it reaches the man, it turns back for the house. This is repeated until the man gets home and lets the dog in.
How many miles does the dog cover from being let off the leash to being let in the house?
