To find the total surface area of a rectangular prism, you need to calculate the area of each of its six faces and then add them all together.
The formula for the surface area of a rectangular prism is:
2lw + 2lh + 2wh
Given dimensions:
Length (l) = 24 inches
Width (w) = 30 inches
Height (h) = 20 inches
Calculating the area of each face:
- Front and back faces (lw): 24 * 30 = 720 sq. in. each
- Top and bottom faces (lh): 24 * 20 = 480 sq. in. each
- Side faces (wh): 30 * 20 = 600 sq. in. each
Adding the areas of all faces:
2(720) + 2(480) + 2(600) = 1440 + 960 + 1200 = 3600 sq. inches
Therefore, the total surface area of the rectangular prism is 3600 square inches.
