Question

A living room is 1,400 cubic meters. If there are 3.6 x 10' particles of dust per cubic meter, how many

particles of dust are there in the living room?
A) 5.04 x 102 particles
B) 5.46 x 1012 particles
C) 6.04 x 1013 particles
D) 6.44 x 1013 particles

Answer 1

Answer: 5.04x
`10^(4)` particles

in your situation is choose : A

Step-by-step explanation:

the volume of the living room is 1,400
`m^(3)`, and there are 3.6 x
`10^(1)` particles of dust /
`m^(3)`

we will convert the room volume to scientific notation = 1.4 x
`10^(3)`
`m^(3)`

then, the total number of particles will be the product of the two numbers, which is 1.4 x
`10^(3)`
`m^(3)` times 3.6 x
`10^(1)` particles/
`m^(3)` = 5.04x
`10^(4)` particles
