Ahot air balloon holds 4,328 cubic meters of helium. the density of helium is 0.1785 kilograms per cubic meter.
how many kilograms of helium does the balloon contain, rounded to the nearest tenth of a kilogram?
3,747.9 kg
3,875.3 kg
772.5 kg
4,383.2 kg

C. 772.5 kg

Step-by-step explanation:

We have been given that a hot air balloon holds 4,328 cubic meters of helium. The density of helium is 0.1785 kilograms per cubic meter.

To find the amount of helium in the balloon, we will use density formula.

Upon substituting our given values, we will get:

Upon rounding our answer to nearest tenth, we will get:

Therefore, the balloon contains 772.5 kilograms of helium and option C is the correct choice.

your answer is d 2,500
