    Answer:

    Volume = 112cm^2

    Density = 0.45 g/cm^2 (2.s.f)

    Explanation:

    Volume of a cube is found by multiplying its height by its length by its width.

    We are given the values: l = 7cm, w = 8cm, h = 2cm, so to find the volume we just need to multiply them all together:

    V=lwh

    V = (7)(8)(2)

    The volume of the cube = 112cm^2

    Density is found by dividing mass by volume.

    We are given the mass (50 grams) and we have just found the Volume (112cm^2), so we can just divide them to find the density:

    p (symbol for density) = m/v

    p = (50)(112)

    The density of the cube is 0.45 g/cm^2 (2.s.f.)

    Hope this helped!
