Answer with Step-by-step explanation:

Rectangular prism means a cuboid

Surface area of cuboid is given by:

2(lb+bh+hl)

where l is the length

b is the width

and h is the height

We are given l=8 ft

b=15 ft

and h=9 ft

Surface area= 2(8×15+15×9+9×8)

= 2×327

= 654

Hence, surface area of rectangular prism is:

654 square feet
