The surface area of a rectangular prism is found by adding up the areas of all six faces.
The formula for the surface area of a rectangular prism is:
Surface Area = 2lw + 2lh + 2wh
Given the dimensions:
Length (l) = 2 feet
Width (w) = 3 feet
Height (h) = 4 feet
Plugging in the values into the formula:
Surface Area = 2(2)(3) + 2(2)(4) + 2(3)(4)
Surface Area = 12 + 16 + 24
Surface Area = 52 square feet
Therefore, the surface area of the rectangular prism is 52 square feet.
Here is the net of the rectangular prism to help visualize the six faces:
Front and back faces: two squares of 2x4 feet
Top and bottom faces: two rectangles of 2x3 feet
Left and right side faces: two rectangles of 4x3 feet
