Answer: c. 1.11 g/cm³
Step-by-step explanation:
The formula for determining the volume of the rectangular block is expressed as
Volume = length × width × height
The rectangular block of wood measures 3cm by 6 cm by 4 cm. Therefore,
Volume = 3 × 6 × 4 = 72 cm³
The formula for determining density is expressed as
Density = mass/volume
Mass of wood = 80.0 grams
Volume of wood = 80/72 =
1.11 g/cm³
