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? (Density: D = )
A. .1828 g/cm3
B. .3254 g/cm3
C. 3.073 g/cm3
D. 68.92 g/cm3

Answer 2

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 $V =$ $a$³

$V = (4.1 cm)$³ = 68.921 cm³

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

Thanks,
