Answer:
694 ft²
Step-by-step explanation:
Calculate the area of all 6 walls, noting that the front and back faces are congruent as are the 2 side faces and top/bottom faces
area = 2(13 × 8.5) + 2(11 × 8.5) + 2(13 × 11)
= 221 + 187 + 286 = 694 ft²
1$ = 100 cents, 1 hour = 60 minutes
$3.00/hour = (3*100) cents / (1*60)minutes
= 300 cents/60 minutes
= 5 cents/minute
