Light as a Feather The feathers in a pillow have a total mass of 59 grams. The pillow is in the shape of a rectangular prism measuring 51 cm by 66 cm by 7 cm. A steel anchor is shaped like a square pyramid. Each side of the base measures 20 cm, and its height is 28 cm. The anchor's mass is 30 kg. 1. What's the density of feathers in kilograms per cubic meter? 2. What's the density of steel in kilograms per cubic meter? 3. What's the volume of 1,000 kg of feathers in cubic meters? 4. What's the volume of 1,000 kg of steel in cubic meters?
