Cross-Sectional Area of a Rectangular SolidThe volume of any rectangular solid, including a cube, is the area of its base (length times width) multiplied by its height: V = l × w × h. Therefore, if a cross section is parallel to the top or bottom of the solid, the area of the cross-section is l × w.

Draw a horizontal line on the graph paper that is the length of your profile line. Draw vertical lines above your starting and ending points. Label the y-axis (vertical lines) with elevations making sure that your scale goes from highest to lowest on your cross-section (see step 3).
Contour lines can never cross one another. Each line represents a separate elevation, and you can't have two different elevations at the same point.
CALCULATING AREA ON A MAP
- Measure length in cm and convert to m / km.
- Measure width in cm and convert to m / km.
- Apply formula – L x W.
- Write the answer in km² / m².

A cross profile shows a cross-section of a river's channel and valley at a certain point along the river's course. Cross profile of a river. Near the source of a river there is more vertical erosion as the river flows downhill, using its energy to overcome friction (A).
Create a new row in the table and in cell B4 paste the formular =(C3+B3)/2. Then copy this into all the cells in the trapeziod row. This should calculate the values for this row for you. It is possible to use Excel to draw the cross-section and calculate the area rather than drawing it by hand on graph paper.
Steps for Finding the Volume of a Solid with a Known Cross Section
- Sketch the base of the solid and a typical cross section.
- Express the area of the cross section A(x) as a function of x.
- Determine the limits of integration.
- Evaluate the definite integral V=b∫aA(x)dx.

- Click in the drawing area to indicate the start point of the section line.
- Click in the drawing area to indicate the end point of the section line.
Vertical exaggeration (VE) is a scale that is used in raised-relief maps, plans and technical drawings (cross section perspectives), in order to emphasize vertical features, which might be too small to identify relative to the horizontal scale.
To determine the amount of vertical exaggeration used to construct a profile, simply divide the real-world units on the horizontal axis by the real-world units on the vertical axis. If the vertical scale is one 1"=1000' and the horizontal scale is 1"=2000', the vertical exaggeration is 2x (2000'/1000').
The cross-sectional area of a wire is directly proportional to the square of its radius (A = πr2), and hence to the diameter of the wire as well. Therefore, if we increase the diameter of the wire two times, its cross-sectional area will increase four times.
Cross section, in nuclear or subatomic particle physics, probability that a given atomic nucleus or subatomic particle will exhibit a specific reaction (for example, absorption, scattering, or fission) in relation to a particular species of incident particle.

More collisions mean more resistance. Second, the cross-sectional area of the wires will affect the amount of resistance. Wider wires have a greater cross-sectional area. In the same manner, the wider the wire, the less resistance that there will be to the flow of electric charge.
Cross section is an area. Diameter is a linear measure. That cannot be the same. The cross section or the cross sectional area is the area of such a cut.
Also the resistance of a conductor is inversely proportional to its cross-sectional area (A) as R ∝ 1/A. Thus doubling its cross-sectional area would halve its resistance, while halving its cross-sectional area would double its resistance.
The nominal (see below) cross-sectional area for standard conductors including the following: Class 5&6: Maximum diameter of any component strand of the conductor.
In the United States, smaller conductors are measured using the American Wire Gauge (AWG). With the gauge system, the higher the number is, the smaller the cable will be. For larger wires, circular mils are used. MCM sizes, also called kcmils (kilo-circular mils), are for even larger cables. A 1000 (4/0) wire, has a .
