Answer 1

The surface area of the rectangular prism is

`A=2\lbrack l\text{ }* w+l* h+w* h\rbrack`

From the given figure

l = 5 km, w = 3 km, h = 4 km

Substitute them in the rule above

`\begin{gathered} A=2\lbrack5*3+5*4+3*4\rbrack \\ A=2\lbrack15+20+12\rbrack \\ A=2\lbrack47\rbrack \\ A=94 \end{gathered}`

The surface area is 94 km^2
