Given is a rectangular prism with,
width, w = 6.4 in
height, h = 5.9 in,
length, l = 6.8 in.
The surface area of a rectangular prism can be calculated as,
[tex]S=2(wl+hl+hw)[/tex]Substituting, the values, we have,
[tex]S=2(6.4\times6.8+5.9\times6.8+6.4\times5.9)=242.8[/tex]Thus, the surface area is 242.8
