The image above represents genoid height anomaly for crustal and mantle densities.

To compute for genoid height anomaly for crustal and mantle densities, one essential parameter is needed and this parameter is **height (h _{1}).**

The formula for calculating genoid height anomaly for crustal and mantle densities:

Δh ≃ 6h_{1} (0.7 + 0.066h_{1})

Where:

Δh = Geoid Height Anomaly for Crustal and Mantle Densities

h_{1} = Height

Let’s solve an example;

Find the genoid height anomaly for crustal and mantle densities when the height is 12.

This implies that;

h_{1} = Height = 12

Δh ≃ 6h_{1} (0.7 + 0.066h_{1})

Δh ≃ 6(12) (0.7 + 0.066(12))

Δh ≃ (72) (0.7 + (0.792))

Δh ≃ (72) (1.492)

Δh ≃ 107.424

Therefore, the **genoid height anomaly for crustal and mantle densities **is **107.424 m.**
