Final answer:
The weight of Ben's dog is 20 kg.
Step-by-step explanation:
To find out how many kilograms (kg) Ben's dog is, we need to multiply the volume of the dog by its density. The volume of Ben's dog is given as 2 m³ and its density is given as 10 kg/m³. Therefore, the weight of the dog can be calculated as:
Weight = Volume × Density
Weight = 2 m³ × 10 kg/m³
Weight = 20 kg
Therefore, we are solving for the weight of Ben's dog, which is 20 kg.
