Idk, but I can help you find the strength needed to destroy a pyramid.
Yes, I'm a giant asshole and a grammar nazi and I don't care ovo.

"Built around 2600bc, the Great Pyramid of Giza in Egypt is 146m high and has a square base of side 230m. Find the work (against gravity) required to build the pyramid if the density of the stone is estimated at 2000 kg/m3."

I'll give an exemple of how it fragments objects if you wish

Using the Great Pyramid of Giza for reference, it has a weight of 6.5*10^9 kg and is made of white limestone, that has density of 2600 kg/m^3, so volume would be: 6.5*10^9/2600 = 2.5*10^6 m^3.
Shear strength of limestone vary from 10 - 50 J/cc (frag. and v. frag. respectively), so the range is 25 - 125 TJ

thank you very much

Take into account that is the Great Pyramid, you would need to use the cubic law (don't remember its name) to re-scale the weight if the other pyramid has a different size.

it is from a light novel, so we didn't get an actual size besides it being the biggest structure in the verse. There is a webcomic, but it differs too much to really use

You'd simply pixel scale to the humans to find the height and base, find the weight through the density of stone I posted above, and then voila.

Pyramid aren't completely solid, calculate volume alone would be a little unaccurate, using the Great Pyramid (or any other real pyramid) as reference is more accurate.

hmmm, wished to ask, where should I pixel scale? The computer is kinda oldscgool and doesn't have many preinstalled programs

Microsoft Paint. Every computer has it and it works quite well. It's what I use.

Basic Paint should work, if it gives you the mount of pixel per trace then it should work.

How do I get the height?
its base lenght is 684m
its base width is the same.

Take a person, get his pixel length. Take the height, and do its pixel length. Then cross multiply.

well, I can do that, but would that not give an inflateted height as I am not starting from the middle but by the side?

well, if it counts its 1389.45 meters tall.
which gives 2.45×109 of volume.
That would make roughly 9 to 47 (possibly 18 to 94, as sometimes the humans are half as big )
