Can someone try and answer this quickly please. It’s due by the end of the day. Also, show your work. I will award Brainliest! Thanks!

If there are 3 shelves 0.3m wide and there is a 0.05m gap on both sides between the shelves and the wall, all you have to do is add.
0.3 + 0.3 + 0.3 + 0.05 + 0.05 which is equal to 1.00 or C. 1
Since all the measurements on the problem seem to be on the same axis, you should be able to simply do addition.
The answer should just be 1.
