Estimating Concrete:
1. Find the total cubic footage (CF) to be covered.
L * W = SF
(D / 12) * SF = CF
2. Ready-Mix Concrete.
60# bags: CF * 2 = # of bags
90# bags: CF * 1.5 = # of bags
3. Form Materials.
2x4 - 4' stakes; (L * W) / 2 = # of stakes
Form Boards
D / form board width = # of runs.
(L + W) * 2 = LF per run
LF per run * # of runs = Total LF
