"Painting the entire exterior surface of a cube with edge length S = 1.26 meters reduces paint level by 2 inches in a cylindrical paint can with radius R = 3.24 inches. Assuming the paint is put on with a uniform thickness, calculate this thickness in inches." Hmm... I don't think the paint can height is necessary... at least, it wasn't given in the problem. I started out by calculating the volume of the 2 inches removed from the can, and, knowing that the volume would stay the same, tried to figure out how to put the volume onto the surface of the cube. That's where I got stuck. Any ideas? Thank you!

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.
A cylinder containing 246 cubic centimeter of gas at a pressure of 101 kPa when its temperature is 526 K. Given that its temperature is unchanged when the pressure was increased by a factor of 3.9, Determine the new volume of the gas (In cubic centimeter). Note: Your answer must be in cubic centimeter, however, do not include the unit, just enter the magnitude that corresponds to the final volume in cubic centimeter.

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).
Assume you have a drop of 2 cm3 falling down. A) If the drop is a cube, what is its surface area? (Hint, volume of a cube = L3. Surface area of a cube=6*L2, where L is the length of the cube, and the factor of 6 as a cube has 6 faces). B) For the same drop, what is its surface area if it is a sphere? (Hint, volume of a sphere=4/3*pi*R3. Surface area of a sphere=4*pi*R2.) C) Find the surface area to volume ratios of both objects. Which object (sphere or cube) has a lower surface area to volume ratio? Which shape does the drop favor?
