I guess it depends where you live. I've always poured it right on grade using 2500 psi, 1x4 forms with no vapor barrier, rebar, WWM or fiber, but it's always been clay or sand. Tool joints 1/4 the depth, making no more than 100 SF sections and broom finish. Tool a joint at all places where concrete butts into a sidewalk/building at a 90* or you'll get a crack

We always calculate a yield of 65 SF per yard, so I come up with 83 yards for 5400 SF (unless my math is wrong again).
