Three:
1) The area of the cross-sectional rectangle end
2) The area of the rectangle joining the longer side of the cross-sectional rectangular ends
3) The area of the rectangle joining the shorter side of the cross-sectional rectangular ends
Then the surface area of the rectangular prism is twice the sum of these three areas.
The surface area of a cylinder prism has round shape and the surface of a rectangular prism has a square shape.
surface area of a rectangular prism is the formula: 2lw+2wh+2lh
12
LxWx2
Squared. When you find surface area, you are only finding the area of the shapes that make up the three-denominational shape.
I am not sure that a rectangular prism is in any position to care!
Suppose that the area of the rectangular base is: lw then if the height is: h the surface area is: lw + lh + wh I believe that formula is for the surface area of a rectangular prism...
Given the surface area of a rectangular prism, there are infinitely many rectangular prisms possible.
For the same base dimensions (base area) and the same height, the rectangular prism has more surface area.
The surface area is 88.
Surface area = 2lw + 2wh + 2hl
You can't derive the volume from the surface area.
