    Did you make a typo on 0/78 inches?

  • Chemistry - ,

    yes. i meant 0.78 sorry.

  • Chemistry - ,

    Convert 0.78 inches to ?cm. Then
    volume of the cube = (?cm)^3.
    density = mass/volume. You have mass and volume, solve for density.

    Then mass = volume x density.
    volume 25.0 cc.
    density from above.
