Master professional techniques for calculating volumes of irregular shapes. From simple decomposition to advanced 3D scanning, learn the method that works best for your specific situation.
Standard volume formulas only work for regular geometric shapes like cubes, cylinders, and spheres. But real-world objects are often irregular, complex, or combinations of multiple shapes.
of real-world objects are irregular
lost due to inaccurate estimates
wasted on manual calculations
Shapes that can be broken into standard forms
L-shaped building: Rectangle 1 + Rectangle 2
High (95-98%)
Medium
Small objects that can be submerged
Rock volume: 250ml - 200ml = 50ml = 50cm³
Very High (98-99%)
Easy
2D irregular shapes with known height
Irregular floor plan: 45 full + 12 partial squares
Good (85-92%)
