What is the total surface area of the inside and outside of a container in the shape of a rectangular prism with length of 5 meters, width of 3 meters, and height of 2.2 meters?

  • Math - ,

    "rectangular prism" , fancy word for plain ol' box

    Outside surface area
    = 2(5x3) + 2(5x2.2) + 2(3x2.2)
    = 68.2

    Unless we know the thickness of the material used, we might just want to assume that the inside surface area is the same ??
