Question

Cubes are three-dimensional square shapes that have equal sides. What is the density of a cube that has a mass of 12.6 g and a measured side length of 4.1 cm

Answer 1

D = m / V 
m = 1.26 g 
V = s^3 = 4.1^3 = 68.921 cm^3 
so 
D = 12.6 / 68.921 = 0.1828 g/cm^3 
and this corresponds to choice (a)

Answer 2

A the answer is A, took a test
