Area = 1000.00 ft^2 = 92.9 m^2
volume of concrete = 8ft x 1000ft^2 = 18.9m^3
price of concrete = $1,000.00/m^3 x 18.9m^3 = $18,877.90

rebar = A393 mesh = 0.00157m^3/m^2 concrete
weight of rebar = 0.00157 x 92.9 x 7.85MT/m^3 = 1.146MT
price of rebar = $10,000/MT x 1.146MT = $11,455.64
Total Price = $18,877.90 + $11,455.64 = $30,333.54 (say $31,000)
