Question

Which statement is correct?

Answer 1

I'm pretty sure is the block B

Answer 2

Answer: Block A has the greatest density.

Explanation:

Density is defined as the mass contained per unit volume.

$Density=\frac{mass}{Volume}$

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

$V=lbh$

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 = $2cm\times 4cm\times 6cm=48cm^3$

$Density=\frac{3kg}{48cm^3}=0.0625kg/cm^3$

b) Block B:

mass = 1 kg

Volume = $2cm\times 4cm\times 6cm=48cm^3$

$Density=\frac{1kg}{48cm^3}=0.02kg/cm^3$

c) Block C:

mass = 2 kg

Volume = $2cm\times 4cm\times 6cm=48cm^3$

$Density=\frac{2kg}{48cm^3}=0.04kg/cm^3$

Thus Block A has greatest density.
