Answer:
(d) 290.125 in²
Explanation:
You want to know the total surface area of a rectangular prism 3 in by 4.52 in by 18.25 in.
Area
The surface area is given by the formula ...
A = 2(LW +H(L +W))
Using the given values, this is ...
A = 2((3 in)(4.25 in) +(18.25 in)(3 in +4.25 in)) = 290.125 in²
The total surface area of the prism is 290.125 in², matching choice D.
