Mathematics for IGCSE & O level - Similarity (Section 1 - No. 30)
A model car is built to a scale of 1:50. The volume of the real car's trunk is 2 m³. What is the volume of the trunk in the model?
0.000016 m³
0.0008 m³
0.0016 m³
100 m³
Explication
Scale factor = 50. The volume scale factor = 50^3. Volume of model = 2 / (50^3) m³ = 2/125000 = 0.000016 m³
