Answer:
To find the surface area of a rectangular prism, we can use the formula:
SA = 2(lw) + 2(wh) + 2(LH)
where SA is the surface area, l is the length, w is the width, h is the height, and L is the length.
Substituting the given values, we get:
SA = 2(2.9 x 1.23) + 2(1.23 x 7) + 2(2.9 x 7)
SA = 5.634 + 17.22 + 40.6
SA = 63.454 m^2
Therefore, the surface area of the rectangular prism is 63.454 square meters.
