What is the surface area of a rectangular prism whose dimensions are 3 3/4 dm x 4 1/2 dm x 5 dm in square decimeters? (1 point)
The formula to find the surface area of a rectangular prism is 2lw + 2lh + 2wh, where l is the length, w is the width, and h is the height.
Given dimensions:
Length = 3 3/4 dm = 3.75 dm
Width = 4 1/2 dm = 4.5 dm
Height = 5 dm
Surface Area = 2(3.75*4.5) + 2(3.75*5) + 2(4.5*5)
Surface Area = 2(16.875) + 2(18.75) + 2(22.5)
Surface Area = 33.75 + 37.5 + 45
Surface Area = 116.25 square decimeters
Therefore, the surface area of the rectangular prism is 116.25 square decimeters.
