    the dimensions of the rectangular prism are;

    10cm, 11cm, 12cm

    Step-by-step explanation:

    The formula for volume of a rectangular prism is;

    V = L x w x h

    Where;

    V = Volume

    L = Length

    w = width

    h = height.

    We are given;

    volume = 1320 mL

    From conversion, 1mL = 1cm³

    Thus, volume; v = 1320 cm³

    A dimension = 10 cm

    We don't know whether this is the length, height or width.

    Let's assume this is the Length.

    Thus,

    10 x w x h = 1320 cm³

    Divide both sides by 10 to give;

    wh = 1320/10

    wh = 132 cm²

    Now, we are told that length, width and height are consecutive whole numbers.

    Thus, the possible numbers could be;

    8,9,10 or 9, 10, 11 or 10,11,12

    From all these, the only one gives a product of 1320cm³ are 10, 11 and 12

    Thus, the dimensions of the rectangular prism are;

    10cm, 11cm, 12cm
