Find the surface area of a rectangular prism with a height of 3.1 cm, a length of 7.4, and a width of 5cm. do not round your answer
The surface area of a rectangular prism can be calculated using the formula:
Surface Area = 2lw + 2lh + 2wh
Given:
Length (l) = 7.4 cm
Width (w) = 5 cm
Height (h) = 3.1 cm
Substitute these values into the formula:
Surface Area = 2(7.4)(5) + 2(7.4)(3.1) + 2(5)(3.1)
Surface Area = 2(37) + 2(22.94) + 2(15.5)
Surface Area = 74 + 45.88 + 31
Surface Area = 150.88
Therefore, the surface area of the rectangular prism is 150.88 square cm.
