Question

The density of a feather is about 0.0025 gram per cubic centimeter and the density of a brick is about 1.84 grams per cubic centimeter. You have 1000 grams of feathers and 1000 grams of bricks. What volume of each do you have?​

Answer 1

To find the volume for each, divide the mass by density. The feathers occupy 400,000 cm³ and the bricks occupy 543.48 cm³.

Step-by-step explanation:

In this physics problem, we are given the density of feathers and bricks and the total mass of each to find their corresponding volumes. Density, which is mass per unit volume, is given in units of grams per cubic centimeter (g/cm³). To find the volume of each given the mass, we use the formula:

Volume = Mass ÷ Density

The density of feathers is 0.0025 g/cm³ and for bricks is 1.84 g/cm³. With a mass of 1000 grams for each substance, we calculate the volumes as follows:

Volume of feathers:

1000 g ÷ 0.0025 g/cm³ = 400,000 cm³

Volume of bricks:

1000 g ÷ 1.84 g/cm³ = 543.48 cm³ (rounded to two decimal places)

Therefore, you have 400,000 cm³ of feathers and 543.48 cm³ of bricks.
