Context: After decades of development, ASML shipped the first production extreme ultraviolet lithography machine in 2013. These machines produce light in the 13.5 nm wavelength range when a high-energy laser is focused on microscopic droplets of molten tin to produce a plasma, which then emits EUV light. The light is bounced off Zeiss mirrors that are the flattest mirrors in the world, on to the surface of a silicon wafer to deliver the designs for the chip. ASML's best-selling EUV product has been the Twinscan NXE:3600D, which costs up to $200 million. Shipping the machine requires 40 shipping containers, 20 trucks and three Boeing 747s. As of 2022, ASML has shipped around 140 EUV systems, and it is the only company to manufacture them.

ASML is working on the next generation of EUV systems, with the first shipments to customers for R&D purposes expected to take place at the end of 2023. The platform is designated High-NA as it will increase the numerical aperture (NA) from 0.33 to 0.55, and each system is expected to cost $300 million.


Question: Based on this passage, how many Boeing 747s are required to ship 10 of ASML's best-selling EUVs?

The best-selling EUV is the Twinscan NXE:3600D, and it takes 3 Boeing 747s per EUV, so 30 Boeing 747s are required to ship ten Twinscan NXE:3600Ds.
