Answer: 3.04m^2
Step-by-step explanation: Rectangular Prism (or Cuboid):
The surface area of a rectangular prism can be found by adding up the areas of all its individual faces.
A rectangular prism has six faces: front, back, top, bottom, left side, and right side.
The formula to find the surface area of a rectangular prism is:

Pyramid:
The surface area of a pyramid is the sum of the area of its base and the areas of its triangular faces.
The formula to find the surface area of a pyramid varies depending on the shape of the base and the number of triangular faces, but a general formula is:
