Allie was setting up a fish tank in her room. She needed to find a tank that would fit on her table. What metric unit should she use to record the volume?

the liter is still used, but the official metric (SI) unit is dm^3

To find the suitable tank size for Allie's table, she should consider using the metric unit of liters (L) to record the volume. Liters are commonly used to measure the capacity or volume of liquid substances, such as water in a fish tank.

To determine the appropriate tank size, Allie can follow these steps:
1. Measure the length, width, and height of the table where she wants to place the fish tank, using a metric measuring tool like a ruler or measuring tape.
2. Record these measurements in centimeters (cm).
3. Multiply the three dimensions together (length x width x height) to get the volume of the space available on the table.
4. Convert the volume from cubic centimeters (cm³) to liters (L) by dividing the volume by 1000, since 1000 cm³ = 1 L.
(For example, if the calculated volume is 5000 cm³, then the equivalent volume in liters would be 5000 cm³ / 1000 = 5 L.)
5. With the calculated volume in liters, Allie can now search for fish tanks with a capacity below or equal to that volume.

By using the metric unit of liters, Allie can accurately determine the appropriate tank size to fit on her table.
