A cylindrical barrel is half full of honey. Its total weight with the honey is 50 kilograms. When empty, the barrel weighs 10 kilograms. What is the total weight of the barrel when it is completely full of honey?
90 kilograms
An empty barrel weighs 10 kg, so half a barrel of honey weighs 50 - 10 = 40 kg. A full barrel of honey weighs twice that amount (80 kg) plus the empty barrel's weight (10 kg), totaling 90 kg.
