Question

a cube measuring 2cm on each side weights 5g, willit sink or float

Answer 1

Answer:

Volume of the cube = Length ^3 = 2^3 = 8cm^3

Density = (mass) / (volume) = (5g / 8cm³) = 0.625 gm/cm³ .

The cube will sink in any liquid whose density is less than 0.625 gm/cm³.

It will float in water, whose density is 1 gm/cm³.
