Section Modulus of Rectangular Section Solution

Follow our step by step solution on how to calculate Section Modulus of Rectangular Section?

FIRST Step Consider the formula

z = \frac{B H \cdot (D^{2})}{6}

Next Step Substitute values of Variables

∴

z = \frac{20mm \cdot ({100.1mm}^{2})}{6}

Next Step Convert Units

∴

z = \frac{0.02m \cdot ({0.1001m}^{2})}{6}

Next Step Prepare to Evaluate

∴

z = \frac{0.02 \cdot ({0.1001}^{2})}{6}

Next Step Evaluate

∴

z = 3.34000333333333E-14m³

Next Step Convert to Output's Unit

∴

z = 3.34000333333333E-05mm³

LAST Step Rounding Answer

∴

z = 3.3E-5mm³
