Answer:
The real plane is 48 ft long.
Explanation:
Since the model airplane was built at a scale of 1 inch to 6 feet, this means that for every 1 inch on the model there is 6 feet on the real plane. We know that the model is 8 inches longs, therefore we need to multiply it's length by 6 and we will have the correct answer. We have:
real length(ft) = [model lengh (in)]*6
real length(ft) = 8*6 = 48 ft
The real plane is 48 ft long.
