Next Step Convert Units

∴

U v = \frac{(1 - 2 \cdot 0.3)}{6 \cdot 1.9E+11Pa} \cdot {(3.5E+7Pa + 4.7E+7Pa + 6.5E+7Pa)}^{2}

Next Step Prepare to Evaluate

∴

U v = \frac{(1 - 2 \cdot 0.3)}{6 \cdot 1.9E+11} \cdot {(3.5E+7 + 4.7E+7 + 6.5E+7)}^{2}

Next Step Evaluate

∴

U v = 7582.1052631579J/m³

Next Step Convert to Output's Unit

∴

U v = 7.58210526315789kJ/m³

LAST Step Rounding Answer

∴

U v = 7.5821kJ/m³
