I need to be able to refer to an object which has/needs something applied to it or used on it. A couple of examples:
- one liter of paint is needed to paint an area of 10m².
- 6 birthday candles are needed to decorate a birthday cake.
- 1000 bricks are enough to lay a 100m long pavement track.
What I'm trying to describe here is : area, birthday cake, pavement.
The best I've come up with is 'object of application'. I looked it up on Google, and it mostly refers to terms in objective programming, so that wasn't a great deal of help.
Any suggestions ?
