The h = 10. See also. The base is 20" square or 400 in 2. The lateral surface area formula is: L.S.A = 2πrh L. S. A = 2 π r h The surface area is usually measured in square units. The surface area of a rectangular prism formula is SA=2(lw+hw+lh), where l=length h=height w=width Rectangular prism is a solid three dimensional object, it has either six flat surfaces of rectangles or four rectangles with two squares. Sometimes you need more than a solution. We know that, surface area of rectangular prism is calculated as, S u r f a c e a r e a = 2 (w i d t h × l e n g t h) + 2 (l e n g t h × h e i g h t) = 2 (7 × 12) + 2 (12 × 3) = 168 + 72 = 240 i n 2. Answer: The area of the rectangle is W X L = 7 x 5 cm 2 = 35 cm 2. In this case P = 2(5.6) + 2(4.3) = 11.2+8.6 = 19.8. Lateral or Curved Surface Area of Cylinder Formula. You can think of the lateral surface area as the total surface area of the prism minus the two triangular areas at the top and bottom of the prism. Formulas for surface area of rectangular prism : Formula Used: Volume V = (1 / 3) π h (r1 2 + r2 2 + (r1 * r2)) Slant Height S = √ ((r1 - r2) 2 + h 2) Lateral Surface Area L = π (r1 + r2) s If you want to calculate the surface area of a rectangular tank, you can use the formula: A = 2lw + 2lh + 2wh where l is length, w is width, and h is height. lateral surface area cylinder To find the area of the sides of this cylinder, we would multiply the circumference by the height. To understand where the formula for the surface area of a triangular prism comes from, let’s have a look at this derivation: The lateral surface area part is easy to calculate in this case.
