Answer:
$220\ cm^2$

Explanation:

We know that the surface area of a rectangular prism is given by :=

$\text{S.A.}=2(lw+wh+hl)$ , 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 :-

$\text{S.A.}=2((5)(4)+(4)(10)+(5)(10))\\\\\Rightarrow\text{S.A.}=220\ cm^2$

Hence, the surface area of the given rectangular prism =
$220\ cm^2$
