Answer: [tex]220\ cm^2[/tex]
Step-by-step explanation:
We know that the surface area of a rectangular prism is given by :=
[tex]\text{S.A.}=2(lw+wh+hl)[/tex], where l is the length, w is width and h is height of rectangular prism.
According to the given dimensions, the surface area of given rectangular prism will be :-
[tex]\text{S.A.}=2((5)(4)+(4)(10)+(5)(10))\\\\\Rightarrow\text{S.A.}=220\ cm^2[/tex]
Hence, the surface area of the given rectangular prism = [tex]220\ cm^2[/tex]
