Answer
$311827$ $lb$
Work Step by Step
1. Convert $kg/m^{3}$ to $lb/yd^{3}$ using conversion factors: $1m^{3}= 1.30795yd^{3}$ and $1kg = 2.20462 lb$. The density of water is $1000kg/m^{3}$.
$p = \frac{1000kg/m^{3} \times 2.20462 lb/kg }{1.30795yd^{3}/ m ^{3}} = 1685.55 lb/yd^{3}$
2. Calculate the mass using density and volume:
$m = p \times V = 1685.55 lb/yd^{3} \times 185yd^{3} = 311827 lb$
