Answer:
A = 504inch
Step-by-step explanation:
Formula = A = 2(wl + hl + hw)
or A = 2wl + 2lh + 2hw, where w is the width, the l is the length, and the h is the height.
2wl = 6inch × 12inch = 72inch × 2 = 144inch
2lh = 12inch × 10inch = 120inch × 2 = 240inch
2hw = 10inch × 6inch = 60inch × 2 = 120inch
Then add all
144inch + 240inch + 120inch = 504inch
A = 504inch
