Answer:

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.
