how do you find the surface area of a rectangular prism?

Aug 13th, 2014

  • Find the area of two sides (Length*Height)*2 sides
  • Find the area of adjacent sides (Width*Height)*2 sides
  • Find the area of ends (Length*Width)*2 ends
  • Add the three areas together to find the surface area
  • Example: The surface area of a rectangular prism 5 cm long, 3 cm. wide and 2 cm. high = 5*2*2 + 3*2*2 + 5*3*2 = 20 + 12 + 30 = 62 cm2.
