Hi

I'm trying to create a spreadsheet that will work out how many days it will take to build a wall. Your help would be very appreciated as my brain is going to explode.

I know how many bricks are in a metre squared and how many bricks can be laid in a day by a single bricklayer.

The issue is that a wall can only be built to a certain height before it falls over, so the bricklayer has to return the next day when the mortar has set.

So how long would this wall take to build and how to calculate if the length, height and amount of builders change?

Length =17.5m(variable)

Height =1.8m(variable)

Max Height in a day =1.4m(fixed)

Amount of bricks in a m2 =60(fixed)

Amount of bricklayers =2(variable)

Amount of bricks laid per bricklayer per day =275(Fixed)

Its easy to work out in my head as it is obvious that the bricklayers would have to come back an extra half day to finish off but what if the wall was 100m long and 10m high?

I assume this is an algebra question as it has variables, if I'm wrong please tell me which forum to post in
