my boyfriend has just recently started a new job and is strugling to work out the required amount of materials needed to fill holes for example he dug a hole so deep and wide and he couldnt work out how much material to order to fill it could someone please tell us if there is a graph or tool that works it out for you. thanks

Most of the idiot ways of doing it involve cutting a perfectly cuboid hole - which no one ever does.
There are a bunch of 'rule of thumb' ways - like looking at the pile of waste generated, and figuring out 'that's half of it - that's a quarter - that's an eighth' - then measure the eighth in whatever your unit of measurement is going to be - litres? barrowloads? kilos? and multiply back up.
Or cut a 'model' hole that's half as wide, half as deep - and
about the same shape - and measure the waste from that.
He'll probably find that if he admits he's struggling to someone who's not a complete eejit, they'll admit that they struggled to begin with, too, and might even tell him how they do it. No one's born knowing how to do this stuff.
The difference between a fool and an eejit - a fool knows about a tenth of what they, one day, will know, which is perfectly respectable. Eejits know everything they're ever going to know. You can guess my opinion of that...

Volume required = Area of the base x depth.
If the base is square, then area of base = a x a = a^2 where 'a' is the length of 1 side of the square.
If the base is rectangular, then area of the base = a x b where 'a' and 'b' are the lengths of the two adjacent sides of the rectangle (length x width)
If the base is circular, then the area of base is Pi times r^2
or (Pi times Diameter) divided by 4
To calculate how many bags you need to fill the hole,
Divide the volume of the hole by the volume of the material in the bag will fill.

It is pretty simple geometry, if a hole is 6 feet deep 6 feet long and 6 feet wide it is 6x6x6 or 216 cubic feet there are 27 cubic feet of material in 1 cubic yard so 216 Divided by 27 = 8 cubic yards of material to fill the hole

yeah yeah yeah... be nice... everyone has struggled at one time, and this is a perfectly legit question.
1) the volume calculation of length* width*height is fantastic.... except when you realize that sand/fill is compressible....so if he is using sand to fill it with, which he probably is, then that will have to be compacted every so many inches...
2) if it doesn't NEED to be compacted, teh weight of the soil fill alone will compact the underlying soils.
3) what i'm trying to say is that if you figure out the volume of the hole, you are going to have less material than you actually need due to settlement of fines into voids, and the compressibility of a soil.
if he needs 8 yards of soil and they come in 10 yd trucks, have him order 10 yds and see how far that gets him. It should be cut and dry from there.

You must do volume calculation. By a book about geometry, and with formulas for different form of bodies.
The cube has volume a x a x a when a is the side length.
The volume for a ditch with length l, withe w and depth d is :
l x w x d.
Lenght 10m, withe 1m and depth 1m has a volume 1o cubic meters.
Cylinders has volume 3.14 x r x r. r is the radius.
There are fomulas for many types of volumes. By the book and start calculating.

Just measure the hole, if its 10 x 10 x 10, then you need 1000 of volume to fill it

it all depends on the phase of the moon on a full moon you will need more .overfill hole so when settles you wont have indentation in ground.some say this is bull but them are the ones who dont pick up shovels and know nothing about how things work outside of science theories

apply simple mathetical formula to find out the volume of the hole.
