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 m
ratelena [41]

Answer:

A.  0.1828 g/cm³

Explanation:

Hi there,

Density's well known formula is Greek letter rho:   ρ =\frac{m}{V}= \frac{m}{a^3}    where m is the mass, and V is volume. Since the volume in question is a cube, the volume of a cube is simply the edge length V = a³

V = (4.1 cm)³ = 68.921 cm³

ρ = \frac{12.6 g}{68.921 cm^3} = 0.1828 g/cm³

Thanks,
