piece of wood that measures 3.0 cm by 6.0 cm by 4.0 cm has a mass of 80.0 grams. What is the density of the wood? Would the piece of wood float in water? Explain.

Answer 1

To find the density of the wood, we can use the formula:

Density = Mass / Volume

The mass of the wood is given as 80.0 grams.

The volume of the wood can be calculated by multiplying its length, width, and height:

Volume = 3.0 cm * 6.0 cm * 4.0 cm = 72.0 cm^3

Now we can substitute the values in the formula to find the density:

Density = 80.0 grams / 72.0 cm^3 ≈ 1.11 grams/cm^3

So, the density of the wood is approximately 1.11 grams/cm^3.

Whether the piece of wood would float in water can be determined by comparing its density with the density of water, which is about 1 gram/cm^3.

Since the density of the wood (1.11 grams/cm^3) is greater than the density of water (1 gram/cm^3), the wood will sink in water.
