Maria has a rectangular fish tank that is 3 feet long, 2 feet wide, and 1.5 feet tall. To find out how much water it can hold, we need to calculate the volume of the tank. The formula for the volume of a rectangular prism is given by:
$$ V = l imes w imes h $$
where $$ V $$ is the volume, $$ l $$ is the length, $$ w $$ is the width, and $$ h $$ is the height. How much water can the fish tank hold?
