How do I calculate the yield of a 100m explosion?

Title is the question

The explosion happens 10 meters above ground, has near-total fatality, and can cause damages to armored vehicles.

i’m not smart enough to calculate anything nor explain it

but this explains how to do it n also provides a calculator if you have the size of the explosion

also it has an equation here u can use if the explosion is above the ground

Air blast radius (near-total fatalities) Yield: Y = ((x/0.28)^3)/1000 with Y in megatons of TNT and x the radius in km
