Find the surface area of a rectangular prism with a height of 3.1 cm, a length of 7.4 cm, and a width of 5 cm. (Do not round your answer.)
To find the surface area of a rectangular prism, you need to calculate the sum of the areas of all six faces.
The formula for the surface area of a rectangular prism is:
2lw + 2lh + 2wh
Given:
l = 7.4 cm
w = 5 cm
h = 3.1 cm
Plugging in these values into the formula:
Surface area = 2(7.4)(5) + 2(7.4)(3.1) + 2(5)(3.1)
Surface area = 74 + 45.8 + 31
Surface area = 150.8
Therefore, the surface area of the rectangular prism is 150.8 square centimeters.
