Check the picture below.

so let's add all sides and that'd be the area of the rectangular prism.

$\stackrel{\textit{top and bottom}}{2(4\cdot 7)}+\stackrel{\textit{left and right}}{2(4\cdot 4)}+\stackrel{\textit{front and back}}{2(4\cdot 7)}\implies 56+32+56\implies 144$

What is the surface area of a polyhedron with measurements 4cm x 4cm x 7cm?

Y/3+1=6. subtract one from both sides to get y/3 = 5. multiply both sides by 3 to get y = 15.
