Best ResponseYou've already chosen the best response.0truck is 3.5m so vertical distance from top is (63.5) = 2.5 truck is 3m wide, 1.5m on either side of center line imagine a triangle formed from right side of top of truck to top center of arch d is hypotenuse and is the longest distance from arch to truck top corner
