Answer:
406 square inches
Explanation:
The net of a rectangular prism has 6 rectangular faces.
In this prism, the dimensions of the faces are:
• 2 rectangles with length 7 in. and width 5 in.
,
• 2 rectangles with length 7 in. and width 14 in.
,
• 2 rectangles with length 14 in. and width 5 in.
Next, we find the surface area of the prism:
[tex]\begin{gathered} \text{Surface Area}=2(7\times5)+2(7\times14)+2(14\times5) \\ =2(35)+2(98)+2(70) \\ =70+196+140 \\ =406in^2 \end{gathered}[/tex]
The surface area of the rectangular prism is 406 in².
