Work Step by Step
a. The baby weighs 3.91 kg which is equal to 8.61 lbs. and 8 oz. The baby's length of 51.4 cm is equal to 20.24 inches.
(3.91 kg * 2.20462 = 8.61 lbs) (51.4 cm * 0.393701 = 20.24 inches)
b. The circumference of the earth at the equator is 25,000 mi which is equal to 40,233.6 km and 40,233,600 meters.
(25,000 mi * 1.60934 = 40,233.6 km) (40,233.6 * 1000 = 40,233,600 meters)
c. The rectangular solid measures 1.0 m by 5.6 cm by 2.1 dm, its volume is 0.001168 cubic meters, 11.68 liters, 4,059.2 cubic inches, and 0.0414 cubic feet.
(1.0 m * (5.6 cm / 100) * (2.1 dm / 10) = 0.001168 cubic meters) (0.001168 m^3 * 1000 = 11.68 liters) (1.0 m * (5.6 cm / 2.54) * (2.1 dm / 2.54) = 4,059.2 cubic inches) (0.001168 m^3 * 35.3147 = 0.0414 cubic feet)
