Answer:
Maximum number of cups completely filled
= 19500 ÷210
= 92.857 (5 s.f.)
Since there is not enough water to fill the 93rd cup, at most 92 cups can be filled completely from the water container.
Explanation:
1L= 1000mL
① Ensure all the units of volume are the same. Here, I am converting all the units into mL.
Amount of water in the water container
= 19.5 L
= 19.5(1000) mL
= 19500 mL
② Find the number of cups that can be filled.
Since 1 cup has the volume of 210 mL, let's find the number of sets of 210 mL there are in 19500 mL.
19500 ÷210
= 92.857
= 92 (maximum possible number of cups)
Although 92.857 cups would be theoretically be rounded up to 93 cups, we have to write 92 cups as the 93rd cup will not be completely filled.
