Surface area is measured in square units, such as square meters (m²), square centimeters (cm²), or square inches (in²), depending on the system of measurement used.
To find the area of something
Square kilometres for lakes or towns, square metres for rooms or gardens, square centimetres for pictures or sheets of paper are some common units and the magnitudes that they would be used to measure.
(7*x)/2 = area in square units
Surface area of three dimensional figures are measured in square units whereas their volumes are measured in cubic units
Both volume and surface area are fundamental concepts in geometry that describe properties of three-dimensional shapes. They are used to quantify the space an object occupies (volume) and the extent of its outer surface (surface area). Additionally, both measurements can be influenced by the shape and dimensions of the object; for example, increasing the size of an object generally increases both its volume and surface area. Furthermore, they can be expressed in terms of the same units, such as cubic units for volume and square units for surface area, but they represent different aspects of the object's geometry.
A globe is a sphere in which two mathematical formulae are used to calculate its surface area and its volume: Surface area of a sphere = 4*pi*radius2 in square units. Volume of a sphere = 4/3*pi*radius3 in cubic units.
Square units are used to measure the area of something.
Area = ( length of a side)2
You could use h*BA cubic units, provided that the units used for BA are squares of units used for h. If BA is in square centimetres and h is in metres, the formula will give a answer which is not easy to understand.
Area in square units = pi*radius2
is it used in squre units
Surface Area is technically the same as area if we are dealing with 2-dimensional surfaces. But, it is mostly used to find an area of a 3-dimensional object.
