Answer: 52 square feet

Explanation:

The surface area of a rectangular prism is given by :-

S.A.=2(lw+wh+hl) , where l is length , w is width and h is height of then prism.

Given: Dimensions of the rectangular prism :
l* w* h= 2 feet by 3 feet by 4 feet

Then , the surface area of a rectangular prism will be:-

$S.A.=2(2(3)+(3)(4)+(2)(4))\\\\\Rightarrow\ S.A.=52\text{ inches}^2$

Hence, the surface area of a rectangular prism= 52 square feet
