You need to measure the density of a rectangular-shaped metal block (density=mass/volume). You measure the mass using an electronic balance accurate to 1 g, and find the mass to be 132 g. You measure the three sides using a millimeter rule and find the sides to be 23.1 cm by 4.2 cm by 0.4 cm. From this you calculate the volume as 38.81cm and the density to be 3.401 g/cm³ (note: this is what your calculator shows-the numbers are not necessarily rounded to the correct place.) How many significant figures should your final answer is rounded to? O A. 1 O B. 2 О С.3 O D. 4

In the United States, most people measure weight in pounds and height in feet and inches. When weight W is measured in pounds and height h is measured in inches, the BMI formula is BMI = 703W/h². Identify the product that produces the English-to-metric conversion factor of 703. A person with a BMI between 25.0 and 30.0 is considered overweight. If a person is 6'11" tall, for what range of mass mmin ≤ m ≤mmax will he be considered overweight? Mmin = mmax = kg kg
