Describe the Water Displacement Process:
1) Measure a Graduated Cylinder with water to an exact amount (ex: 100mL) 2) Drop your irregular shaped object and record the new volume (ex: 115mL) 3) Subtract the difference of the new volume from the original volume (115-100 = 15mL) Volume of the irregular object is 15mL

Katie's book measures 3cm in length, 7cm in height, and 1 cm in width. She used a large triple beam balance and found the mass to be 63 grams. Calculate the density of Katie's book.

Mass= 4 g Volume= 3 cm x 7cm x 1cm = 21 cm3 Mass / Volume= 2 = 63/21 = Density of Katie's book is 3 g/cm3
