2 = x -15

add 15 to both sides

17 = x

17+2 = 2(17)-15

19 = 34 -15

Whats the density of an object with the length of 5.0 cm a height of 3.0 and width of 15.0 cm and a mass of 24 grams
Sphinxa [80]

Answer:

The density of the object is 0.1067 grams per cubic centimeter. (Rounded off to 4th decimal)

Step-by-step explanation:

Density = [Mass/Volume]

Here we have been given the dimensions of the object.

Volume = Height * Width * Length

Volume = 3.0cm*15.0cm*5.0cm

             =225cm^{3}

Now we can substitute the Mass and the Volume to the density equation.

Density = [Mass/Volume]

             =\frac{24grams}{225cm^{3} }

             =0.1067 grams per cubic centimeter. (Rounded off to 4th decimal)
