    How much material do I need to fill a human mould?

    I need to work out how much material it will take to fill a human mould based on a certain set of figures that I have, and I don't know how to convert them.

    The material covers 64.1m≤/tonne @ a depth of 10mm.

    The figures I have for the mould are: height 1.7m, and average diameter 0.82m (waist).

    Please can someone show me how to work this out because I have worked it out to be 1.38t of material, and this seems rather high.

    Thanking you in advance.

    The density of the material is 1/(64.1 \times 0.01) \approx 1.56 tonnes per cubic metre, the human body has a density of \approx 1 tonne per cubic metre, so the mass of meterial will be about 1.56 times the mass of a human body \sim 110-120 kg so yes your answer is high by something like an order of magnitude.
