# Surface Area Calculator - Oblique Prism

Posted by Dinesh onOnline geometry calculator to calculate surface area of an oblique prism.

The lateral surface area of an oblique prism is the sum of the areas of the faces, which must be calculated individually.

### Cavalieri's Principle

If two solids have the same height and the same cross?sectional area at every level, then they have the same volume. This principle allows us to derive a formula for the volume of an oblique prism from the formula for the volume of a right prism.
