Figure it out stupid.
For the same base dimensions (base area) and the same height, the rectangular prism has more surface area.
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...
They are both 3 dimensional shapes having surface area and volume.
Pyramids come in different shapes. It all depends on the shape of your pyramid.
A rectangular pyramid you use 1/3 or divide 3 in the product but a triangular prism you use 1/2 or divide 2 on the product.
If they have the same height, then the rectangular prism will require more paint. (Having the same height the prism will have more surface area than the pyramid).
The answer will depend on what A and H are!
A rectangular pyramid.
Rectangular prism = 6Triangular prism = 5 Triangular pyramid = 4 Rectangular prism: it is still 6 Rectangular pyramid = 5.
