how much fluid (volume) can spread up to two square meters?

Question

if fluid drops from a barrel to the ground and when the barrel is empty there are roughly 2 square meters of fluid on the ground. How many liters (roughly) of fluid were inside the barrel?

Answer 1

2 liters

Resting water is an average of 1 millimeter high.

2 * .001 = .002 meters^3

= 2 liters

Answer 2

You need enouhg information to determine the height of the fluid on the ground. It is indeterminant in your problem statement so you can't ansower the question numberically. You acan assume the fluid is h meters thick on the ground so the volume is:

V = 2 m^2 x h m = 2h m^3
