A block of foam has a mass of 10 g, a volume of 60 cm3, and a length of 30 cm. What is the density of the foam? (If necessary, round your answer to three decimal places.)

Respuesta :

AL2006
The density is

(Mass)/(volume)

= 10/60 = 1/6 g/cm^3 . (1.667)

If you already know the volume, then the length doesn't matter.

The density of the foam is [tex]0.167 \;g/cm^3[/tex].

Given the following data:

  • Mass of block of foam = 55.0 grams
  • Volume of foam = 60 [tex]cm^3[/tex]
  • Length of foam = 30 cm.

To find the density of the foam;

Density can be defined as mass all over the volume of an object.

Simply stated, density is mass per unit volume of an object.

Mathematically, the density of a substance is given by the formula;

[tex]Density = \frac{mass}{volume}\\\\Density = \frac{10}{60}[/tex]

Density = [tex]0.167 \;g/cm^3[/tex]

Therefore, the density of the foam is [tex]0.167 \;g/cm^3[/tex].
