The topographic map below represents a location in North America. Points A through C are locations on the map. Elevations are in meters.

1. The elevation at Point A is

1 60 m 3 140 m

2 100 m 4 300 m

2. In which direction is the stream flowing?

1 northwest 3 southwest

2 northeast 4 southeast

3. What is the approximate length of the stream

between point A and point B?

1 5 km 3 9 km

2 7 km 4 10 km

4. Which side of Lookout Hill has the steepest

slope?

1 north 3 east

2 south 4 west

In the SI system, volume can be expressed in two ways, one is in liters and the other as a unit of distance “cubed” such as cm3. When using distance the “cube” is because you must multiply a distance times a distance times a distance. It is very important that all three distances are in the same unit such as cm or m or mm. For a cube the formula is length X width X height. Once you have the volume and the mass, it is easy to calculate the density of an object, that is, the amount of stuff in a certain space. To find the density, the formula is mass/volume. Work the following problems for practice; you’ll need it on an upcoming lab and chapter test.

You must have the correct
UNITS in order to get credit!

1.  ______What is the volume of a box measuring 1m X 5m X 6m? (Remember units)

2.  ______What is the volume of a cube measuring 5cm on each side?

3.  ______What is the volume of a box measuring 3cm X 6cm X 4cm?

4.  ______What is the volume of a box measuring 8mm X 10cm X 5cm? (Be careful – units!)

For the next problems you’ll need to figure density. Remember that density is mass/volume.

5.  ______An iron cube measures 10cm X 10cm X 10cm. What is its volume?

6.  ______If the same iron cube weighs 7.9g, what is its density in g/cm3?

7.  ______What is the density of a cube of water measuring 2cm X 4cm X 1cm, with a mass of 8g?

8.  ______What is the density of a block of wood measuring? 9cm X 2cm X 6cm with a mass of 5.4g?
