I say a 100' because I have to run from the whole length of the house then out the side and back to where the shed is.
If you want outside lights at both the house and the shed that you can control from either end then you will want four wires plus ground and it may be hard to find UF cable in ten gauge with four insulated conductors. In that case you can bury a PVC conduit under one foot of earth if you protect the circuit with a GFCI. If you bury the conduit under eighteen inches of earth you will not have to provide GFCI protection and you can avoid any possibility of nuisance tripping of the circuit do to moisture in the underground conduit or cable. You would also need to make sure that the conductors serving the outside light never enter the interior of the shed or that there is a switch that will deenergize the entire circuit were it originates in the house.
