First, find out the volume of water in the cup: 50.24x16 = 803.84cm3, then find out the volume of the cup: 803.84/4x5 =1004.8cm3, and then subtract the volume of water from the volume of the cup to find out how many milliliters are needed to fill the cup:1004.8-.

200.96 cubic centimeters =200.96 milliliters

So it takes 200.96 ml to just fill the quilt.

Hope to adopt
