Consider that the external radius of each pipe in the image is 0.60 m and that they are on top of a truck bed whose upper part is at $1.30 \mathrm{~m}$ from the ground. The drawing represents the rear view of the pipe stacking.
The recommended safety margin for a vehicle to pass under an overpass is that the total height of the vehicle with the load be at least $0.50 \mathrm{~m}$ less than the height of the overpass span.
Consider 1.7 as an approximation for $\sqrt{3}$. What should be the minimum height of the overpass, in meters, for this truck to pass safely under its span?
(A) 2.82
(B) 3.52
(C) 3.70
(D) 4.02
(E) 4.20
