What is the density of a block with a mass of 420 g and a length of 2cm, 3cm wide, and 1cm long

Step-by-step explanation:

Find the volume first.

V = l * w * h

l = 2 cm

w = 3 cm

h = 1 cm

V = 2 * 3 * 1 = 6 cm^3

Density = mass / volume

Density = 420 grams / 6 cm^3

Density = 70 grams / cc^3

Kind of large. Check your givens.
