One inch is equal to 2.54 cm. Draw a line that is 1 inch long, and mark the centimeters on the line. Draw a cube that is 1 inch on each side. Draw lines on each face of the cube that are 1 centimeter apart. How many cubic centimeters are there in 1 cubic inch?

You are using a Pasteur pipet and want to determine the volume of liquid dispensed in a drop. You add 12 drops into a 10 mL graduated cylinder and observe the volume shown below. What volume (in mL) is dispensed in each drop?

c) A metal sample has a mass of 7.56 g. The sample is placed into a graduated cylinder previously filled with 20.00 mL of water (enough to cover the sample). If the final volume in the cylinder is 21.68 mL, what is the density of the substance? Consult Table 1.4 on page 19 of the textbook to identify the metal.

The dimensions of a rectangular object were obtained as shown below. Use the data to determine the area of the rectangle. Make sure your final answer is reported to the correct number of significant figures: Width 3.56 cm 1sam Length 5.425 cm

The chemist measures the volume of the unknown liquid as 0.615 L and the mass of the unknown liquid as 385. g. Calculate the density of the liquid. Be sure your answer has the correct number of significant digits. Is it possible to identify the liquid? If it is possible to identify the liquid, do so.

You find a penny with a mass of 2.50 g and a volume of 0.266 cm3. Is this penny pure copper? (The density of copper is 8.96 g/cm3)

Suppose you have two 100-mL graduated cylinders. In each cylinder, there is 20.0 mL of water. You also have two cubes: one is lead, and the other is aluminum. The density of lead and aluminum are 11.3 g/mL and 2.70 g/mL respectively. Each cube measures 3.0 cm on each side. After you carefully lower each cube into the water of its own cylinder, what will the new water level be in each of the cylinders?   Express your answer to three significant figures and include the appropriate units.

Mr Fast runs 3.7km. Mr Slow runs 630m. How much further does Mr Fast run than Mr Slow?   Add together 4.5km, 120m and 50cm     I have four pieces of string. They are 3m, 45cm, and 25cm long. What total length in cm do I have?   A square field has a perimeter of 3.6 km. What is the length of one side in metres?  A mountain peak is 4.26 km above sea level. A climber is 540m below the summit. How high above sea level is the climber?

Suppose you have two 100-mLmL graduated cylinders. In each cylinder, there is 44.0 mLmL of water. You also have two cubes: one is lead, and the other is aluminum. The density of lead and aluminum are 11.3 g/mLg/mL and 2.70 g/mLg/mL respectively. Each cube measures 3.0 cmcm on each side. After you carefully lower each cube into the water of its own cylinder, what will the new water level be in each of the cylinders? Express your answer to three significant figures and include the appropriate units.

Bronze is an alloy made of copper (Cu) and tin (Sn). Calculate the mass of a bronze cylinder of radius 9.31 cm and length 36.28 cm. The composition of the bronze is 79.42 percent Cu and 20.58 percent. Sn and the densities of Cu and Sn are 8.94 g/cm3 and 7.31 g/cm3, respectively. What assumption should you make in this calculation? Enter your answer in scientific notation.
