Glad to help :D

Answer 4

I agree with answer, but we should not just give the answer if we can. Knowing how to convert units is a huge skill in most computational Science!

Unit analysis:
\(\text{Volume}\times \text{Density} = \cancel{ \text{cubic meters}} \times \dfrac{\text{kilograms}}{\cancel{\text{cubic meters}}} = \text{kilograms}\)
The cubic meters cancel like any numbers in both numerator and denominator, leaving kilograms.
2,850 [[cubic meters]], times 0.1685 [[kilograms per cubic meter]] = 480.225 [[kilograms]].
