Activity 5.4 Calculating Properties of Solids
Introduction
Have you ever stopped to think why it is that you are able to float in water? The reason has to do with the concept of buoyancy. The volume of water that your body displaces has weight. The weight of the displaced water pushes upward on you, while the weight of your body pushes down. If the weight of the displaced water pushing upward is greater than your weight, then you will rise out of the water to a point where equilibrium has been achieved. This means that the weight of your body that is submerged in the water, let’s say from your shoulders down, is equal to the weight of the volume of water that your body is displacing. Another way to explain this is to look at

a. What is the volume of the wood board? Precision = 0.00
b. What is the surface area of the wood board? Precision = 0.00
c. What is the weight of the wood board? Precision = 0.00
d. If one gallon of paint will cover 57,600 square inches, how many gallons would be needed to give two coats of paint to 25,000 boards? Round your answer to the nearest gallon.
e. What will the total cost be to ship the 25,000 boards to a facility for assembling into the finish kit form if the shipping rate is $4.25 per pound?
f. If a 2 x 6 (which means the actual dimensions of the board are 1.5 in. x 5.5 in.) milled from the same wood (and therefore has the same density) weighs 3.2 lb, how long is the board?
3. Calculate the properties of your puzzle cube pieces.
a. Fill in the following table with the appropriate information. Be sure to use SI units. You may need to re-measure your puzzle pieces using a metric ruler.
Piece identity
Number of cubes
Mass (g)
Surface area (cm2)
Volume (cm3)
b. Add Density as the header in the final column of the table. Be sure to indicate appropriate units. Calculate the density for each piece and record the value in the table.
c. Create a scatterplot in Excel displaying mass and volume as the variables.
Which variable (mass or volume)
2. Collect data: Click Slice. Choose a piece of Styrofoam and drag it onto the Material Investigation tray. Record the mass and volume, then calculate the density by dividing the mass by the volume. Replace the piece, and then repeat for the remaining pieces.
Purpose: To learn about the international system of units (SI), to become familiar with common lab equipment and techniques, to gain proficiency in determining volume, mass, length, and temperature of a variety of items using common laboratory measurement devices, to learn to combine units to determine density and concentration, and to use laboratory equipment to create serial dilutions and determine the density and concentration of each dilution.

a. What is the total balance of Jessie Robinson 's real estate account? (0.5 points)
Purpose: Weighing objects. Figuring out the density with an object by calculated volume and Archimedes’ Principle.
10. If 12,500 units are produced, what is the total amount of fixed manufacturing cost incurred to support this level of production?
5. Calculate the mass of the water by subtracting “Mass A” from “Mass B.” Record the mass of the water in Data Table 4.
1) In this exercise, you viewed the settlement of costs to finished goods and manufactured output settlement. As noted in the exercise, each should be for $42,000.
1. Question : Which of these statements is most accurate about the amount of rangelands
Next, the data was recorded and was used in the formula to find the density of the 40 pennies.
2. In order to calculate the density of a solid or liquid sample, what measurements are needed?
D. A sample of gold (Au) has a mass of 26.15 g. Given that the theoretical density is 19.30 g/mL,
Swimming is science. When a person swims, they are displacing water. In Ancient Greek times, a physicist named Archimedes discovered the principle of buoyancy. Archimedes Principle states that an object in gravity applies a force, or a buoyancy, to whatever it is surrounded in. When a person submerges him or herself in water, the water levels will rise. The density of a person or object determines if its floatation. If an object is more dense than the water, it will sink. On the contrary, an object lighter than water will float. There are various styles or strokes including breaststroke, freestyle, and more. Freestyle swimming consists of many components that combine to efficiently swim. Physics is a subtle yet
a) Tributary area (on a horizontal plane): AT = (20 ft)(13 ft) = 260 ft2 > 200 ft2
Have you found yourself stuck in the three-meals-a-day cycle for some time now? Well, it might make you feel better to learn that you’re not actually alone. The vast majority of people get hung up on the widely accepted misconception that eating more than the traditional three meals a day constitutes as some sort of dietary failure. While it’s true that eating calorie-laden snacks between meals is no recipe for good health, limiting yourself to the ancient breakfast, lunch and dinner format isn’t doing you any favours either. Forget three square meals a day and most certainly forget snacking in between meals. Your new healthy eating regime consists of six mini meals but while it may be super healthy, sitting down to eat six small meals a day won’t always be convenient which is why we’re going to show you not only why this style of eating habit is healthy, but just how healthy popcorn can make it more convenient, achievable and enjoyable too.
