    Density of an apple.

    Hi,

    This is my first post could someone please help me solve this and show me how you come to the answer?

    A net of 6 apples from Asda has a total mass of 1590g, measured to the nearest 10s, and the volume of one apple is 3.0 x 10to the power of -4cubed. Calculate the density of an apple. Give your answer in scientific notation and to the appropriate number of significant figures.

    DENSITY=MASS/VOLUME (KG/VOLUME)

    Any help would be appreciated

    Just divide 1590/6 to get the (avg) mass of 1 apple. Then divide that by 3x10^{-4}. Finally, convert to the desired units.
