The formula for 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 the dimensions of the rectangular prism:
l = 3 3/4 dm = 3.75 dm
w = 4 1/2 dm = 4.5 dm
h = 5 dm
Plugging these values into the formula:
Surface area = 2(3.75)(4.5) + 2(3.75)(5) + 2(4.5)(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.
What is the surface area of a rectangular prism whose dimensions are 3 3/4 dm × 4 1/2 dm × 5 dm in square decimeters?(1 point)
