Question

If a large marshmallow has a volume of 3 in cubed, and density of .242 g/cm cubed, how much would it weigh in grams

Answer 1

first convert the inches cubed to centimeters cubed. looking at the rate we can write 2 inches cubed = 2 * 16.39 cm cubed 32.78 cm cubed. the equation for density is D= m/v where D is the density M is the mass and V is the volume substitute the values into the equation
0.242= m/32.78 multiply by 32.78 on both sides
the mass is about 7.93 grams
