Safety concerns:
10. Wear closed toed shoes to prevent foot injuries.
11. Where goggles when working with the glass (beaker and graduated cylinder).
13. Do not be involved in horseplay because you might cause the graduated cylinder and beaker to break.
34. If you break the graduated cylinder or beaker never use just your hands use a brush and dustpan to clean up, throw away the glass as told by the teacher.
Procedure:
Part I: Rectangular Solid (Wooden Block)

What pieces of laboratory equipment would you use to measure the properties needed to determine the density of a substance? The piece of laboratory equipment needed to find mass is a balance and for volume a graduated cylinder. 3. Using the properties stated in question 1, write the formula for density. D=m/v 4. What two sets of units can be used to describe density? Why are they interchangeable? The two sets of units used to describe density are grams (g) and milliliters (mL). They are interchangeable because 1g=1mL. 5. A solid block with a length of 6.0 cm, a width of 3.0 cm, and a height of 3.0 cm has a mass of 146 g. What is the block’s density? Show all work. V=lxwxh v=6.0cmx3.0cmx3.0cm= 54cm D=m/v d= 146g/54cm= 2.7g/cm3 6. To determine the density of an irregularly shaped object, a student immersed the object in 21.2 mL of water in a graduated cylinder causing the level of the water to rise to 27.8 mL. If the object has a mass of 22.4 grams, what is the density of the object? Show all work. 27.8mL- 21.2 mL=6.6 mL D=m\v d= 22.4grams/ 6.6 mL=

1035 Words | 5 PagesHow is finding volume different from finding area? d. If you had cubes with a length of 1 centimeter, how many would you need to build the cube in the picture above? Calculating volume of a rectangular prism Rectangular prisms are like cubes, except not all of the sides are equal. A shoebox is a rectangular prism. You can find the volume of a rectangular prism using the same formula given above (V= l × w × h.) Another way to say it is to multiply the area of the base times the height.

As an example, a sheet of paper is 21.6 cm, 216 mm, or 0.216 m wide. In each case, the measurement is precise to 1 mm (which is 0.1 cm and 0.001 m). The first degree of uncertainty is at the mm length.

## Pre Calculous Unit Circle Project Questions

696 Words | 3 PagesThere are two types of special right triangles: 45-45-90 and 30-60-90. The legs on a 45-45-90 triangle are 1 and 1 and the hypotenuse is the square root of 2. The legs on a 30-60-90 triangle are 1 and the square root of 3 and the hypotenuse is 2. If you were to take the three trigonometric functions of either 45 degree angle, you would get the (square root of 2)/2 for both cosine (x) and sine (y) and 1 for tangent (y/x). If you were to take the three trigonometric functions of the 30 degree angle, you would get the (square root of 3)/2 for cosine, ½ for sine and the (square root of 3)/3 for tangent.

## Archimedes' Principle

381 Words | 2 PagesMeasurements of the radius and length of the cylinder provided its volume and theoretical density of 2.74 g/cm^3 which confirmed Archimedes’ Principle. The principle was further confirmed by calculating a 2.99% difference between the buoyant force and the weight of the aluminum cylinder. In the second part, a 30.5 g wooden cylinder was hung from a string and attached to a scale and lowered into the water-filled graduated cylinder as much as could be submerged with the string remaining taut. The wood displaced approximately 12 mLs of water and had an “apparent mass” of 20 g while
