Question

A piece of wood that measures 3.0 cm by 6.0 cm has a mass of 80.0 grams. What is the density of the wood. would it float?

Answer 1

Answer:1.111 g/cm³- Will not float

Step-by-step explanation:

Answer 2

1.111 g/cm³- Will not float

Step-by-step explanation:

• Density may be defined as the mass of an object per unit volume.
• It is calculated by dividing the mass of an object by volume.
• Assuming the piece of wood measures 3.0 cm by 4.0 cm by 6.0 cm and has a mass of 80.0 grams, then we can calculate its density.

• 
  `Density=(Mass)/(volume)`

But; Volume = length × width × height

Volume of the wood = 3.0 cm × 4.0 cm × 6.0 cm

= 72 cm³

Therefore;

Density = 80.0 g ÷ 72 cm³

= 1.111 g/cm³

The density of the piece of the wood is 1.111 g/cm³ and will therefore, will NOT float since it has a higher density than water.
