Question

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 1

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)
