Question

The bedroom of our house is 1200 cubic meters. We know that there are 3.4 x 10^9 particles of dust per cubic meter. Write how many particles of dust are in the bedroom.

Answer 1

To find the total number of dust particles in the bedroom, we need to multiply the volume of the bedroom with the number of dust particles per cubic meter.

First, we have the volume of the bedroom as 1200 cubic meters.

Second, according to the information given, there are 3.4 x 10^9 dust particles per cubic meter.

By multiplying these two values together, we can calculate the total number of dust particles in the bedroom.

So, 1200 (bedroom volume in cubic meters) times 3.4 x 10^9 (dust particles per cubic meter) equals 4.08 x 10^12 dust particles.

Therefore, there are 4.08 trillion dust particles in the bedroom.
