Question

If the average house has 2.8x10^5 particles of dust per cubic meter, how many particles would there be in a 900 cubic meter home?

A) (2.52 × 10^8) particles
B) (2.52 × 10^9) particles
C) (2.52 × 10^10) particles
D) (2.52 × 10^11) particles

Answer 1

The number of particles in a 900 cubic meter home with an average of 2.8x10^5 particles of dust per cubic meter is 2.52 × 10^8 particles.

Step-by-step explanation:

To find the number of dust particles in a 900 cubic meter home, we need to multiply the average number of dust particles per cubic meter by the total volume of the home.

The average house has 2.8x10^5 particles of dust per cubic meter. Therefore, the total number of particles in a 900 cubic meter home would be (2.8x10^5) * (900) = 2.52 × 10^8 particles.

So, the correct answer is A) (2.52 × 10^8) particles.
