RAIN FALL QUESTIONS---CAN'T FIND PART 4 about kg!

Homework Statement

During a thunderstorm, a total of 0.9 inches of rain falls. How much water falls on one acre of land? (1 mi2 = 640 acres) Express your answer in the following ways.

I found ft^3, m^3, and in^3, but I'm stumped on part 4...where it asks for kg??

Homework Equations

I found 564376 in^3, 3267 ft^3, and 92.5111378 m^3 and I know these 3 parts are 100 percent correct?
JUST NEED HELP WITH PART 4 ON HOW TO FIND kg!
Thanks in advance guys!

A relevant equation you will need is density, ρ=m/V.

What is the density of water ?

SORRY!

NOTE: Density of 1000kg/m^3!

Thanks. sorry again

Well then, if you have the formula ρ=m/V, you know 'ρ' and you know 'V', you want to find 'm', rearrange the formula and make 'm' the subject.

i still don't get it? i know my mass is x, what is the density in this problem? Would i take the 1000kg/92.5111378 m^3? and then my volume is 92.5111378 m^3...so I would get m=dv...so d=10.8095 and then v is 92.5111378 m^3, d times v equals 1000?

m=ρV.

You told me density ρ=1000kg/m³

And the volume V=92.5111378m³?

Just substitute into the formula.

SO the answer is 1000kg after doing the math out?
