None. You need a second dimension to calculate square meters.
5*5.5 = 27.5 square meters
Yes
You cannot. Length is only one dimension, square meters is two. Kinda like asking to convert square meters into time.
India has a total land area of approximately 3.287 million square kilometers, which is equivalent to 3.287 trillion square meters.
Linear meters do not convert into square meters, unless you multiply them by another dimension. For example, if you have a yard that is 120 meters long and 100 meters wide, it would have an area of 12,000 square meters.
Area has the dimension of (length)2. So square feet, square yards, square miles, square meters, square centimeters; are all units describing an area. A hectare is an area unit equal to 10000 square meters, and an acre is an area unit equal to 43560 square feet.
0.00064516 is the conversion factor to convert square inches to square meters. However, it must be square inches. If you only have inches, then you will have to multiply by the second dimension to get square inches before converting to square meters.
To work out square meters you need two dimension not just one length.
Total land area in india - 2973190 square kilometers.
You can't get to cubic meters from square meters without another dimension. If you have measured the floor of a box that is 2m x 5m then the floor is 10sqmeters. To get cubic meters, you'd measure the height as well and then multiply it by the floor's area. square meters = Area = one dimension x another dimension cubic meters = Volume = Area x another dimension (which is 3D) Some say, that time is the only other dimension to consider which would give the 3D object the capability to move/morph, likely irrelevant for your question.
6 meters is a distance, while square foot is an area; so it can not be converted. Meters has only 1 dimension, while square foot is 2 dimensional.
