We are tasked to solve for the total liters of water does Sameer was able to drink. To solve this we need to remember that 1 cup is equivalent to 0.236588 liters and then we need to perform the unit conversion. The solution is shown below:
total number of liters = 3 cups * (0.236588 liter / 1 cup)
total number of liters = 0.709764
The answer is 0.7 rounded to the nearest tenth.
