Finally, sometimes the desired value does not directly match the units given but is derived from the calculation required. For example, a sheet of metal that has a volume of 45.5 cm3 has a width of 14.8 cm and has a length 15.9 cm. What is the thickness (that is, the height) of the metal sheet in millimeters?
Carry out the following conversions. Report your answers to the correct number of significant figures
(h) 911 qt to
(i) 44.2 cm to in
(j) 236.4 g to lb
The density of a liquid is 2.30 g/cm³. What is its density in lb/ft³?
1 in = 2.54 cm; 1 lb = 454 g 1 feet = 12 in
Express your answer in decimal notation rounded to the correct number of significant figures.
