The density of ice is 0.92g cm-3 & that of sea water is 1.025g cm-3.Find the total volume of an iceberg which floats with its volume 800cm3 above water?


ANSWER:7809.5cm3

  • PHYSICS -

    Va = Vi - Vb,
    Va = Vi - (Di/Dw)*Vi = 800 cm^3,
    Vi - (0.92/1.025)Vi = 800,
    Vi - 0.898Vi = 800,
    0.102Vi = 800,
    Vi = 800 / 0.102 = 7843 cm^3. = Vol. of
    ice.

    Va = Vol. above water.
    Vb = Vol. below water.
    Di = Density of ice.
    Dw = Density of water.
