First you would multiply 5,3, and 2 to get a volume of 30. Density is mass over volume so you would then divide 129 by 30. You would get 4.3. The answer would be 4.3 g/cm^3

<u>Answer:</u> The density of solid is 4.3g/cm^3

<u>Explanation:</u>

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

V=lbh

where,

V = volume of cuboid

l = length of cuboid = 5 cm

b = breadth of cuboid = 3 cm

h = height of cuboid = 2 cm

Putting values in above equation, we get:

V=5\times 3\times 2=30cm^3

To calculate density of a substance, we use the equation:

Density=\frac{Mass}{Volume}

Putting values in above equation, we get:

\text{Density of solid}=\frac{129g}{30cm^3}\\\\\text{Density of solid}=4.3g/cm^3

Hence, the density of solid is 4.3g/cm^3
