How many yards of concrete - help

[RussMan]

I want to build a small barn, and about half of the footprint will be concrete floor. So assuming a 5" floor, how many yards of concrete would I need for a area of (24' x 10') plus (10' x 5') OR a total of 290 sq ft. ?

24' x 10' @ 5" = 3.70370 Cubic yards
10' X 5' @ 5" =0.77160 Cubic yards
