## anonymous 3 years ago calculate the mass of a cube of copper, each side of which is 15 cm

1. anonymous

so you can determine the volume, its just 15*15*15=3375 m^3

2. anonymous

$\huge V_{cube}=(side)^3$

3. anonymous

after that, you need the density of copper. Multiply the Density by the Volume, and you'll have your solution :)

okay thanks :). this was physics and i was wondering how to actually get the answer, when i was only given one piece of information. So thanks :)

5. anonymous

Anytime @teeny :)

$Mass of Cube = \left( side of cube \right)^{3}$ So the Mass of the copper cube would be (15*15*15)cm = 3,375 $cm ^{3}$

$\rho=\frac mV$$\rho_{\text{Cu}}=8.96 \left[\text {g·cm}^{−3}\right]$
