Chapter 1, Problem 1.100E

An aquarium has a rectangular cross section that is 47.8 in. by 12.5 in.; it is 19.5 in. high. How many U.S gallons does the aquarium contain? One U.S. gallon equals exactly 231 in3.

The longest river in the world is the Nile River with a length of 4145 mi. How long is the Nile in cable lengths, meters, and nautical miles? Use these exact conversions to help solve the problem: 6 ft = 1 fathom 100 fathoms = 1 cable length 10 cable lengths = 1 nautical mile 3 nautical miles = 1 league

A spherical tank has a radius of 175.0 in. Calculate the volume of the tank in cubic inches; then convert this to Imperial gallons. The volume of a sphere is (4/3) r3, where r is the radius. One Imperial gallon equals 277.4 in3.

The first measurement of sea depth was made in 1840 in the central South Atlantic, where a plummet was lowered 2425 fathoms. What is this depth in meters? Note that 1 fathom = 6ft, 1 ft = 12 in., and 1 in. = 2.54 102 m. (These relations are exact.)

0.0715 gal = _____ c m 3 2.27 x 10 4 mL = _____ g a l

A lap in most tracks in the United States is 0.25 mi (English lap). In most countries that use the metric system, a metric lap is 0.40 km. A champion marathon runner covers a mile in about 5.0 min. How many minutes will the runner take to run an English lap? A metric lap?

A sample of vermilion-colored mineral was weighed in air, then weighed again while suspended in water. An object is buoyed up by the mass of the fluid displaced by the object. In air, the mineral weighed 18.49 g; in water, it weighed 16.21 g. The densities of air and water are 1.205 g/L and 0.9982 g/cm3, respectively. What is the density of the mineral?

The total length of all the DNA molecules contained in a human body is 1 1010 miles. The population of the United States is about 300 million. What is the total length of all the DNA of the U.S. population in lightyears? (A light year is the distance that light travels in a year and is 9.46 1015 m.)
