Question

Each edge of two cubes are 2cm 4cm and their volumes are v1 and v2 find v1:v2

Answer 1

Each edge of 1st cube = 2 cm
Therefore, Volume of Ist cube = v1 = (2)^3 = 8 cu.cm.
Each edge of 2nd cube = v2 = 4 cm
Therefore, Volume of 2nd cube = (4)^3 = 64 cu.cm
Therefore, Ratio of their volumes = v1:v2 = 8:64 = 1:8
