In this experiment based on "Science Starters" by T. Trimpe, students learn to calculate density to determine if an object will sink or float. Using a box with a mass of 456 g and dimensions of 12.5 cm x 5.6 cm x 5.6 cm, we calculate the volume and density. The volume is determined by V = length x width x height, resulting in 392 cm³. The density is found using the formula D = Mass ÷ Volume, yielding a density of 1.16 g/cm³. Since the density is greater than that of water, the box will sink!

Find the density of the box below. Mass456 g 12.5 cm 5.6 cm 5.6 cm
The solution … Volume = length x width x height V = 12.5 cm x 5.6 cm x 5.6 cm V = 392 cm3 M = 456 g Density = Mass ÷ Volume D = 456 g ÷ 392 cm3 D = 1.16 g/cm3 **The box would sink!
