Explanation:
We know that the surface area of a rectangular prism is given by :=
, 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 :-
![\text{S.A.}=2((5)(4)+(4)(10)+(5)(10))\\\\\Rightarrow\text{S.A.}=220\ cm^2](https://img.qammunity.org/2019/formulas/mathematics/high-school/oid6v3qgs5hs0l2ahf88vfaigoa15pkr9g.png)
Hence, the surface area of the given rectangular prism =
![220\ cm^2](https://img.qammunity.org/2019/formulas/mathematics/high-school/epaors6e8am5xvcuroho446pywdfh5x1wz.png)
