Question

calculate the mass of a cube of copper, each side of which is 15 cm

Answer 1

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

Answer 2

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

Answer 3

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

Answer 4

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 :)

Answer 5

Anytime @teeny :)

Answer 6

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

Answer 7

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