An object with a mass of 0.255 kg and density of 2.89 g/cm3 measures 34 mm in length and 46 mm in width. What is the height of the object?

Respuesta :

Explanation:

first let's find the volume of the object using the following formula:

d = m/V

we have:

d = 2.89 g/cm^3

m = 0.255 kg = 255 g

so:

V = 255/2.89

V = 88.24 cm^3

The volume of an object is calculated using the following formula:

length x width x height

we have:

lenght = 34 mm = 3.4 cm

width = 46 mm = 4.6 cm

So:

V = length x width x height

88.24 = 3.4 x 4.6 x height

height = 88.24/15.64

height = 5.64 cm

Answer: height = 5.64 cm
