Kayla and Kilee have each packed one flight sized suitcase for a flight to California to see their grandma. Each thinks she has the greatest density in her suitcase. If Kayla's suitcase weighs 20 lbs and measures 1 x .67 x 2 feet, and Kilee's suitcase weights 18 lbs and measures 1.25 x .75 x 1.25 feet, whose suitcase is the most dense? Hint: first calculate the volume of each suitcase and then use weight for mass.

Group of answer choices

Kilee,'s - her suitcase is 15.36 lbs per square foot

Kayla's - her suitcase is 14.9 lbs per square foot

Kayla and Kilee' suitcases have the same density.

Density cannot be calculated for suitcases, as they are not elements.
