Which statement is correct?
block a has the greatest density.
block b has the greatest density.
the density of block a is equal to the density of block b.
the density of block b is equal to the density of block c.

Block A has the greatest density.

Explanation:

Density is defined as the mass contained per unit volume.

To calculate the volume of cuboid, we use the equation:

where,

V = volume of cuboid

l = length of cuboid

b = breadth of cuboid

h = height of cuboid

Putting values in above equation, we get:

a) Block A:

mass = 3 kg

Volume =

b) Block B:

mass = 1 kg

Volume =

c) Block C:

mass = 2 kg

Volume =

Thus Block A has greatest density.
