Calculate area of topo sheet in 1:50 000 scale,
Having following information as below-
No. of grids in Topo sheet -9
Area of one grid -18.50 x 17.10 cm
Solution: Given scale is 1:50000
OR
1cm: 50 000 cm
OR
1cm: 500 m
OR
1cm: 0.5km
2cm -1km
So that,
18.5 cm =9.25 km
17.10 cm=8.55 km
Area of the Grid- 9.25x8.55=79.087 = 79 sq.km.
Area of the one topo sheet 79 x 9=711 sq.km

The surface area of a prism is calculated by adding the area of the walls to the area of the top and bottom. The area of the walls is calculated by multiplying the perimeter of the top by the height of the wall.
b*h for triangle
That depends on the area to be calculated and some examples are:- Area of a circle = pi*radius2 Area of a triangle = 0.5*base*height Area of a rectangle = base*height
The area of a triangle can be calculated with one main formula. That is, A=(b*h)/2, where A is the area of the triangle, b is the base of the triangle, and h is the height of the triangle.
The area of a circle with a known radius can calculated using the following formula where r is the radius : A = Pi(r)2
A 1:1,000,000 scale toposheet covers an area that is 4 times larger than a 1:250,000 scale toposheet. Therefore, you can fit four 1:250,000 scale toposheets within one 1:1,000,000 scale toposheet.
individual practical method with single toposheet
To locate a toposheet number in India, you can refer to the Survey of India’s Topographic Maps, which are organized using a grid system. Each toposheet is identified by a series of numbers and letters that indicate its geographic location and scale. You can access these maps online through the Survey of India’s website or by visiting local offices. Additionally, using the National Map of India can help pinpoint the specific toposheet for a given area.
A toposheet is a detailed map that shows physical and cultural features of a specific area, usually used for navigation and geographic analysis. On the other hand, a degreesheet is used in cartography to measure distances, directions, and angles accurately on a map. Degreesheets are typically used by surveyors and engineers for precise measurements.
Any one who is having Indian citizenship can get toposhhet from Survey of India's office by paying the Price of that particular toposheet.

toposheet can be studied by the information on the data obtained and the markings,colouring done for a area like canals,roads,railways etc...a study of toposheet is a study of topographic sheet....google for more information
