area = 478218 square meter
to find out
What is the economic evaluation
solution
we find first volume that is
volume = area × thickness
volume = 478,218 × 3.65
volume = 1745495.7 m³
and we know density that is 1290 kg/m³
so weight = volume × density
weight = 1745495.7 × 1290
weight = 2251689453 kg × 2.205 lbs
weight = 4964975244 lbs
so price for 4964975244 lbs is
price = × 4964975244
price = $48433333.5
