The Joneses are moving from San Francisco to South Africa. They pack their belongings in rectangular crates and hire a boxcar to ship the crates across land and sea. The crates are made specifically to fit inside the boxcar with their bases facing down. Each crate has a base 15 ft long by 5 ft wide and height 6.5 ft. The boxcar is 60 ft long, 10 ft wide and 13 ft high. How many crates can The Joneses fit into one boxcar?

La sup della base del box e' :
S box=60 x10=600
S crate =15 x5=75
Sulla base del box si possono mettere 600/75=8 crate

8( crate/ strato) x 2 (strati)=16 crates
