Answer:

$9600 \: {ft}^(2) \\$

Explanation:

Area of front rectangle -

= 2 ( length × breadth )

= 2 ( 40 × 30 )

= 2 ( 1200)

$= {2400 \: ft}^(2) \\$

Area of other rectangles -

= 4 ( length × breadth )

= 4 ( 60 × 30 )

= 4 ( 1800)

$= 7200 \: {ft}^(2) \\$

Surface area of the rectangular prism

$= {2400 \: ft}^(2) + {7200 \: ft}^(2) \\ = {9600 \: ft}^(2) \\$
