H is the height of a cylinder. Lateral Surface Area π rs π rr 2 h 2 Base Surface Area π r 2. Area Length Base perimeter 2 Base area Base perimeter is the sum of all sides of a prisms base abc. Finally the total surface area of the cylinder formula is simply the sum of the base surface area and the lateral surface area.

Total SA π R 2 r 2 π Rr R-r2 h2. To find the surface area of a cube use the formula. Capsule Surface Area Volume π r 2 43r a Surface Area 2 π r2r a Circular Cone Surface Area Volume 13 π r 2 h. Circular end SA π R 2 r 2 lateral SA π Rr R-r2 h2.

In this formula a a is the total surface area r r is the radius of the circles at both ends h h is the height and π π is the irrational number that we simplify and shorten to 3141595 3141595 or even shorter 314 314. Try this and see if you get the same answer. As in the previous example we first need to know the base area. In the Mass properties box you can find many material properties.

Two somewhat more complicated formulas are available for base width w w height h h not slant height and base length l l. A height-weight formula validated in infants children and adults J Pediatr 1978 9362-66. Surface area of a triangular prism. Where R and r are the radii of the ends h is the height.
