Question

units of measurement assessment 2025x
find the density of a 2.0 cm x 2.0 cm x 2.0 cm cube with a mass of 1024g.
m
÷t÷
d×v
8.0 g/cm3
128g/cm3
12 g/cm3
6.0 cm3

Explanation:

Step1: Calculate volume of cube

$V = l\times w\times h=2.0\ cm\times2.0\ cm\times2.0\ cm = 8.0\ cm^{3}$

Step2: Calculate density

The formula for density is $D=\frac{M}{V}$. Given $M = 1024\ g$ and $V = 8.0\ cm^{3}$, then $D=\frac{1024\ g}{8.0\ cm^{3}}=128\ g/cm^{3}$

Answer:

128g/cm3
