to fill the reservoir, of water must be added overnight.

options for units:
square meters
cubic meters
meters

Explanation:

Calculate total reservoir volume

Using the Dimensional Analysis knowledge point

$$
LATEXBLOCK0
$$

Determine remaining percentage needed

The reservoir is currently \(90\%\) full.

$$
LATEXBLOCK1
$$

Calculate volume of water to add

We find \(10\%\) of the total volume.

$$
LATEXBLOCK2
$$

Identify correct unit of measurement

Since we are calculating volume, the appropriate unit is cubic meters.

Answer:

To fill the reservoir, <blank>14,700</blank> <blank>cubic meters</blank> of water must be added overnight.
