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
