Total surface area of a rectangular prism can be calculated by adding the areas of all 6 faces.
The formula for total surface area of a rectangular prism is:
2lw + 2lh + 2wh
Given:
Length (l) = 12 cm
Width (w) = 6 cm
Height (h) = 3 cm
Calculating:
2lw = 2(12)(6) = 144 cm^2
2lh = 2(12)(3) = 72 cm^2
2wh = 2(6)(3) = 36 cm^2
Total surface area = 144 + 72 + 36 = 252 cm^2
Therefore, the total surface area of the rectangular prism is 252 square centimeters.
What is the total surface area of the rectangular prism in square centimeters if the length is 12, the width is 6, and the height is 3
