A composite cube with a side of 2 has a volume of 8 units 3 but a surface area of only 24 units 2. A rectangular prism two cubes wide, one cube long and four cubes tall has the same volume, but a surface area of 28 units 2. Stacking them in a single column gives 34 units 2.
A sphere of radius r has surface area 4πr 2.. The surface area (symbol A) of a solid object is a measure of the total area that the surface of the object occupies. [1] The mathematical definition of surface area in the presence of curved surfaces is considerably more involved than the definition of arc length of one-dimensional curves, or of the surface area for polyhedra (i.e., objects with ...
Within the confines of the Fatah Sagar Lake, there are three small islands; the largest of these is the Nehru Park (4 km 2 (1.5 sq mi) area), which is a popular tourist attraction, the second island (0.06 km 2 or 15 acres area) houses a public park with an impressive water-jet fountain, and the third island (1.2 km 2 area) is the address for ...
The state is served by a substantial road network, providing links between urban centers, agricultural market-places and rural areas. There are 33 national highways (NH) in the state, covering a total distance of 10,004.14 km (6,216.28 mi). [86] The state has a total road length of 269,028 km (167,166 mi).
Geographers increasingly use remotely sensed data to obtain information about the Earth's land surface, ocean, and atmosphere, because it: (a) supplies objective information at a variety of spatial scales (local to global), (b) provides a synoptic view of the area of interest, (c) allows access to distant and inaccessible sites, (d) provides ...
At 25 °C an aqueous solution that has a pH of 3.5 has 10 −3.5 moles H 3 O + (hydronium ions) per litre of solution (and also 10 −10.5 moles per litre OH −). A pH of 7, defined as neutral, has 10 −7 moles of hydronium ions per litre of solution and also 10 −7 moles of OH − per litre; since the two concentrations are equal, they are ...
Monsoon sowing dates vary, occurring toward the end of May in the southern state of Kerala and reaching July in some north Indian states. In other regions like Maharashtra , the west coast of India, and Pakistan, which receive rains in June, Kharif crops are sown in May, June and July. [ 5 ]
Tropical rainforests are characterized by a warm and wet climate with no substantial dry season: typically found within 10 degrees north and south of the equator. Mean monthly temperatures exceed 18 °C (64 °F) during all months of the year. [ 9 ]
