Work out ratio of areas and volumes instantly with clear inputs, formula shown and shareable results.
For similar figures a length ratio of k gives an area ratio of k² and a volume ratio of k³. If the material density is unchanged, mass follows volume and also scales by k³.
Similar figures
lengths : k, areas : k², volumes : k³
The length ratio is 5/3, areas are in the ratio 25/9 ≈ 2.7778 and volumes 125/27 ≈ 4.6296.
Bone cross-sectional strength grows as k² while body mass grows as k³, so scaled-up creatures become proportionally weaker.
