Question

A solid is 5 cm tall 3 cm wide and 2 cm thick it has a mass of 129 g what is the density

Answer 1

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

Answer 2

Answer: The density of solid is
`4.3g/cm^3`

Step-by-step explanation:

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* 3* 2=30cm^3`

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

`Density=(Mass)/(Volume)`

Putting values in above equation, we get:

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

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