    Answer:

    So, to fill the tray completely , he needs 3 bags of sand.

    Step-by-step explanation:

    Tray dimensions,

    length = 0.8 m

    Width = 0.6 m

    height = 0.1 m

    Volume of one sand bag = 17000 cm^3

    Let the volume of the tray is V.

    V = length x idth x height

    V = 0.8 x 0.6 x 0.1 = 0.048 m^3

    Number of sand bags

    n=\frac{0.048}{17000\times 10^{-6}}\\\\n = 2.82

    So, to fill the tray completely , he needs 3 bags of sand.
