What is the density of a wood block that has a mass of 97.5 g and measures 12 cm × 3.33 cm × 4.2 cm? (use significant digits.)?

Answer :

Let us say that:



d = density



v = volume



m = mass



l, w, h are the dimensions of the block





To solve this problem, we must remember that density is
the ratio of mass and volume, that is:



d = m / v





Now let us first calculate for the volume using the
formula:



V = l * w * h



V = 12 cm * 3.33 cm * 4.2 cm



V = 167.832 cm^3





Now we can calculate for the density of the wood block:



d = 97.5 g / 167.832 cm^3



d = 0.58 g / cm^3 (ANSWER)
