Multiply side x side. For example, if you are measuring for new carpet for a room that is 15 feet long and 12 feet wide, and you need to know how much carpet to buy, multiply 15 x 12, which will give you the total surface area.

However, there are different formulae for other shapes like circles or ellipses, or for triangles, or parallelograms and trapeziums,; or their 3-d equivalents.
Total surface area = (2*pi*radius2)+(diameter*pi*height)
Total surface area = (2*pi*r2)+(pi*r2) Area = 300*pi in square units
Total surface area = (2*pi*r2)+(2*pi*r*height) Surface area = 69.11503838 or 69 square units
Surface area including the underneath of the hemisphere = pi*radius2 + 2*pi*radius2 Total surface area = 27pi square units
Use a calculator and you'll get yurh answer
Find the area of each face separately and then add them together for the total surface area.
Find the surface area of each face then add them together to give the total surface area.
Total surface area = (2*pi*radius2)+(diameter*pi*height)
The total surface area! The total surface area! The total surface area! The total surface area!
The surface area of a space figure is the total area of all the faces of the figure
whats the object
If you want to find the surface of something, you must first specify which shape or object you wish to find the surface of, and need to say which area you are looking for, Lateral or Total surface area. Then someone will be able to answer your question.
1. Find the surface area of the whole cylinder 2. Find the area of one of the two circles on either end of the cylinder 3. Multiply the circle's area by two and subtract their area from the total surface area 4. Now you have the surface area of an unclosed cylinder!
Total surface area = (2*pi*r2)+(pi*r2) Area = 300*pi in square units
Total surface area = (2*pi*r2)+(2*pi*r*height) Surface area = 69.11503838 or 69 square units
To find the lateral area of a cylinder, multiply the circumference (πd) by the height (πdh). After you have this, you can find the total surface area by adding twice the area of the base (2πr2).(Lateral area = πdh), (Surface area = πdh + 2πr2).
Unless the context suggests otherwise, the two are the same. However, you may, for example, be required to find the curved surface area of a cylinder and [then] the total surface area. In that case the total surface area would include the areas of the two end faces.
