Although a country is an area on the curved surface of Earth, it is usually calculated as a "flat" surface. The area can be estimated by multiplying the average north-south "height" of a country by the average east-west width.
For "round" areas such as islands, the area can be estimated as the area of a circle of the same average radius.
The total area of a country may be the sum of several distinct areas such as peninsulas and offshore islands. Also, the area can be divided into land areas and water areas within the country's borders.
Example for Egypt: on the map Egypt appears to be about 730 miles N-S and about 540 miles E-W in width. Multiplying gives 394,200 square miles. This is a only a percent or two from the "official" area of 387,048 square miles.
* In kilometers, the measurement is 1175 km by 870 km = 1,022,250 km2.
The official figure is likewise fairly close at 1,002,450 km2.

How would you calculate the surface area t volume ratio?
To calculate the surface area to volume ratio, simply divide the surface area of the object by its volume. This ratio is commonly used in science to understand how efficiently an object exchanges materials with its environment, with a higher ratio indicating better surface area for exchange relative to its volume.
What is the area of Egypt in square miles?
Surface Area: 1,001,450 square km or 386662 square miles
How do you calculate surface density?
Surface density is calculated by dividing the mass of an object or substance by its surface area. The formula is surface density (σ) = mass (m) / surface area (A). The standard unit for surface density is kilograms per square meter (kg/m^2).
What is divided by surface area to calculate pressure?
That is the force F. p = F / Awhere:p is the pressure,F is the normal force,A is the area (surface).
What calculate the surface area of a sphere with a radius of 7 meters.?
To calculate the surface area of a sphere, you can use the formula ( A = 4\pi r^2 ), where ( r ) is the radius. For a sphere with a radius of 7 meters, the calculation would be ( A = 4\pi (7^2) = 4\pi (49) = 196\pi ). Approximating (\pi) as 3.14, the surface area is approximately ( 615.44 ) square meters.
How do you compare the surface are to volume ratio of cells of different size?
You need to:* Calculate the surface area * Calculate the volume * Divide the surface area by the volume
What To calculate the pressure exerted on a surface what quantity is divided by the surface area?
To calculate the pressure exerted on a surface, the force acting on the surface is divided by the surface area. Mathematically, pressure = force / area.
How do you calculate surface area to volume?
surface area divided by volume
To calculate the pressure exerted on a surface what quantity is divided by the surface area?
To calculate the pressure exerted on a surface, the force normal to the surface is divided by the surface area. The formula for pressure is pressure = force / area.
How could you calculate the surface area of a shape?
To calculate the surface area of a shape find the area of each side, and then, add all of the areas together. The sum of the areas is the surface area.
How do you calculate surface area to volume ratio?
You measure or calculate the surface area; you measure or calculate the volume and then you divide the first by the second. The surface areas and volumes will, obviously, depend on the shape.
What is the formula to calculate surface area?
It depends on the shape whose surface area you are interested in.
