Solve for Density: A cube measures 2cm (Hint: the length, width and height is 2 cm). The cube has a mass of 64 grams.

Mass: 64grams Volume: L x W x H : 2cm x 2cm x 2cm 4cm x 2cm 8cm Mass / Volume = 64g/8cm = 8g/cm

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

Daisy used a triple beam balance to find the mass of her crystal sample: 74grams. She used the water displacement process to find her volume. Her initial volume was 50mL, after dropping her crystal, the water level rose to 56mL. Calculate the density of Daisy's crystal sample.
Mass= 74grams Volume= 56ml-50mL = 6mL Mass / Volume = 74g / 6mL Density of the crystal is 12.3g/mL

Katie's book measures 10cm in length, 10cm in height, and 3cm in width. She used a large triple beam balance and found the mass to be 6,000 grams. Calculate the density of Katie's book.
Mass= 6,000g Volume= 10cm x 10cm x 3cm = 300 Mass / Volume= 6,000/300 = 60/3 = Density of Katie's book is 20g/cm
