a swimming pool, in the shape of a rectangular prism, is 50 meters long, 25 meters wide, and 3 meters deep. a liter is the same as 0.001 cubic meters. how many liters of water are needed to completely fill the pool? i understand half of this question. you have to find the volume of the swimming pool by using b x w x h, which is 50 x 25 x 3 = 3,750 meters. what i don't understand is how to covert 750 meters into liters.
