GPT 3.5
The surface area of a rectangular prism is calculated by finding the area of each face and then adding them together.
The formula for the surface area of a rectangular prism is:
Surface Area = 2lw + 2lh + 2wh
Given the dimensions:
Length = 20 ft
Width = 15 ft
Height = 9 ft
Plugging these values into the formula:
Surface Area = 2(20*15) + 2(20*9) + 2(15*9)
Surface Area = 2(300) + 2(180) + 2(135)
Surface Area = 600 + 360 + 270
Surface Area = 1230
Therefore, the surface area of a rectangular prism with dimensions 20 ft long, 15 ft wide, and 9 ft high is 1230 square feet.
