so you can determine the volume, its just 15*15*15=3375 m^3
\[\huge V_{cube}=(side)^3\]
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 :)
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 \[cm ^{3}\]
\[\rho=\frac mV\]\[\rho_{\text{Cu}}=8.96 \left[\text {g·cm}^{−3}\right]\]
