Larry is having a family gathering. Being an above average family with four children, Larry and his wife, Latisha, decide to purchase a new kitchen table.

Before Larry goes to the store he must figure out how large of a table he must purchase.

Larry and Latisha have four kids, each requiring 40 centimeters of space. Adults require 60 centimeters of space. Larry's sister, Enelya, is bringing her husband, and two twin babies which require 30 centimeters each.

Assuming that Larry can only buy tables with a width of 60 centimeters, what is the smallest length possible for the table that Larry must purchase?
