- A 100 mLmL beaker holds 190 gof liquid. What is the liquid's density in SI units?2. You are manufacturing a can which is a perfect cylinder. The ideal volume of the can is 375 cm3. Since the bases of the cylinders are exactly 50 cm2, the volume of the can is V = 50h where h is the height of the can in centimeters. You need to cut the sides of the can so the volume has at most an error of 10 cm³. Give the range of heights the can could have and still meet the required specifications for its volume.An auditorium measures 35.0 m x 25.0 m x 5.0 m. The density of air is 1.20 kg/m3.
