An open metal bucket is in the form of a frustum cone with a height of 21 cm and a radii of its lower and upper ends as 10 cm and 20 cm, respectively. Find the volume of the bucket in liters (L) Using the formula:1.047h(R^2=r^2=Rr) and the conversion factor:1cm^3 = 1mL  . Remember to label your units, round to the nearest thousandths place.

what is the density of aluminum if 3.50 cm3 has a mass of 9.45 g? Please report answer to the correct amount of significant figures.

The density of ordinary air is 1.19 g/L. What is the mass, in kilograms, of the airin a room that measures 14.5 ft x 16.5 ft x 8.0 ft?(Hint: Density is defined as d= m/v, so you need to find the volume of the roomand solve for the mass in the density equation. Make sure you do the appropriateconversions to carry out your operations. Use the correct number of significantfigures to express your answer).

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
