What is the surface area formula for surface area of a prism?

The answer depends on the shape of the prism.If the prism has bases that are polygons with area B square units and perimeter P units, and if theprism is L units long, then the total surface area = 2B + PL square units.The answer depends on the shape of the prism.If the prism has bases that are polygons with area B square units and perimeter P units, and if theprism is L units long, then the total surface area = 2B + PL square units.The answer depends on the shape of the prism.If the prism has bases that are polygons with area B square units and perimeter P units, and if theprism is L units long, then the total surface area = 2B + PL square units.The answer depends on the shape of the prism.If the prism has bases that are polygons with area B square units and perimeter P units, and if theprism is L units long, then the total surface area = 2B + PL square units.


If a square has area is 12 and base is 2.1So what is the height of the square?

If a square has an area of 12 square units, then as all its sides are the same length (by definition), each side will be √12 units longs, ie approx 3.46 units long.If you mean a Rectangle has an area of 12 square units and one side is 2.1 units long, then the other side is:area_rectangle = length × width→ width = area_rectangle ÷ length→ width = 12 units² ÷ 2.1 units→ width = 5 5/7 units ≈ 5.7 units.The "height" is approx 5.7 units long.


What is the area of a square if one side is 40 inches long?

The area of square is : 1600.0


What is the area of a rectangle with a perimeter of 18 units on a coordinate plane?

Assuming that the fact that it is a rectangle means that it cannot be a square, then it can have any value in the interval (0, 20.25) square units. This depends on whether the rectangle is a long thin shape or a near-square.
