Question

If a large marshmallow has a volume of 2.75 in3 and density of 0.242 g/cm3, how much would it weigh in grams? 1 in3=16.39 cm3.

2 Answer


  • •   
    Volume of the marshmallow:

    V = 2.75 in^3          (but, 1 in^3 = 16.39 cm^3)

    V = 2.75 × 16.39 cm^3

    V = 2.75 × 16.39 cm^3

    V = 45.0725 cm^3


    •   Density:

    d = 0.242 g/cm^3


    •  Mass:

    m = d × V

    m = (0.242 g/cm^3) × (45.0725 cm^3)

    m = (0.242 g/cm^3) × (45.0725 cm^3)

    m = 10.907545 g

    m ≈ 10.9 g   <———  this is the answer.


    I hope this helps. =)
