In order to determine how many liters of water the container will have, calculate the volume of the container:
V = (10 m)(7 m)(5 m)
V = 350 m³
next, convert the previous volume to liters, by using the following convertion:
1 m³ = 1,000 L
then, you have:
V = 350 (1,000 L)
V = 350,000 L
Hence, 350,000 L is the amount of water the container will have when it is full
