a student wishes to find the volume of a piece of wood of irregular shape. her experiment requires the use of a small brass object of mass 200g. a] calculate the volume of the brass object. the density of brass is 8.4g/cubic cm.

The volume of the brass object is 23.81 cm³.

Density is the ratio of the mass of a body and its volume. The S.I unit is kg/m³

To calculate the volume of the brass, we make use of the formula below

D = m/V Equation 1

Where D = density of the brass object, m = mass of the brass object, V = volume of the brass object.

make V the subject of equation 1

V = m/D Equation 2

From the question,

Given: m = 200 g, D = 8.4 g/cm³

Substitute these values into equation 2

V = 200/8.4

V = 23.81 cm³

Hence, The volume of the brass object is 23.81 cm³

Volume,

Explanation:

It is given that,

Mass of small object of brass, m = 200 g

The density of brass is 8.4 g/cm³

We need to find the volume of the brass object. Density is equal to mass of an object per unit its volume.

So,

V is the volume of the brass object

So, the volume of the brass object is .

answer: the correct answer id option(d).

explanation:

snell's law refraction:

the angle of refraction =

the angle of incidence =

refractive index of air = = 1

refractive index of glycerol = 1.47

from the given options, the most closest answer to 63.72° is 65° of option (d).
