Answer:
The surface area of a rectangular prism can be calculated using the formula:
Surface Area = 2lw + 2lh + 2wh
where l, w, and h are the length, width, and height of the rectangular prism, respectively.
Given the dimensions of the rectangular prism as:
Length (l) = 38
Width (w) = 20
Height (h) = 20
Substitute the values in the formula to get:
Surface Area = 2lw + 2lh + 2wh
Surface Area = 2(38)(20) + 2(38)(20) + 2(20)(20)
Surface Area = 1520 + 1520 + 800
Surface Area = 3840 square units
Therefore, the surface area of the rectangular prism is 3840 square units.
