SA = 2(wl + hl + hw)
SA = 208
h = 8
l = 6
208 = 2(6w + (8*6) + 8w)
208 = 2(14w + 48)
208 = 28w + 96
208 - 96 = 28w
112 = 28w
112/28 = w
4 = w <==== the width is 4 cm

Answer:
2488 miles
Step-by-step explanation:
The relevant relationship is ...
distance = speed × time
For each leg ...
distance 1 = (264 mi/h) × (2 h) = 528 mi
distance 2 = (490 mi/h) × (4 h) = 1960 mi
Then the total distance traveled in the 6 hours is ...
distance traveled = distance 1 + distance 2 = 528 mi + 1960 mi
distance traveled = 2488 mi
