Volume of Hollow Frustum Solution

Follow our step by step solution on how to calculate Volume of Hollow Frustum?

FIRST Step Consider the formula

V = \frac{h}{3} \cdot ((\frac{n \cdot ({S Long Outer}^{2} + {S Short Outer}^{2})}{4 \cdot \tan (\frac{π}{n})}) + (\frac{n \cdot S Long Outer \cdot S Short Outer}{4 \cdot \tan (\frac{π}{n})}) - (\frac{n \cdot ({S Long Inner}^{2} + {S Short Inner}^{2})}{4 \cdot \tan (\frac{π}{n})}) - (\frac{n \cdot S Long Inner \cdot S Short Inner}{4 \cdot \tan (\frac{π}{n})}))

Next Step Substitute values of Variables

∴

V = \frac{6m}{3} \cdot ((\frac{4 \cdot ({14m}^{2} + {9m}^{2})}{4 \cdot \tan (\frac{π}{4})}) + (\frac{4 \cdot 14m \cdot 9m}{4 \cdot \tan (\frac{π}{4})}) - (\frac{4 \cdot ({10m}^{2} + {5m}^{2})}{4 \cdot \tan (\frac{π}{4})}) - (\frac{4 \cdot 10m \cdot 5m}{4 \cdot \tan (\frac{π}{4})}))

Next Step Substitute values of Constants

∴

V = \frac{6m}{3} \cdot ((\frac{4 \cdot ({14m}^{2} + {9m}^{2})}{4 \cdot \tan (\frac{3.1416}{4})}) + (\frac{4 \cdot 14m \cdot 9m}{4 \cdot \tan (\frac{3.1416}{4})}) - (\frac{4 \cdot ({10m}^{2} + {5m}^{2})}{4 \cdot \tan (\frac{3.1416}{4})}) - (\frac{4 \cdot 10m \cdot 5m}{4 \cdot \tan (\frac{3.1416}{4})}))

Next Step Prepare to Evaluate

∴

V = \frac{6}{3} \cdot ((\frac{4 \cdot (14^{2} + 9^{2})}{4 \cdot \tan (\frac{3.1416}{4})}) + (\frac{4 \cdot 14 \cdot 9}{4 \cdot \tan (\frac{3.1416}{4})}) - (\frac{4 \cdot (10^{2} + 5^{2})}{4 \cdot \tan (\frac{3.1416}{4})}) - (\frac{4 \cdot 10 \cdot 5}{4 \cdot \tan (\frac{3.1416}{4})}))

LAST Step Evaluate

∴

V = 456m³
