This 3rd grade math problem

How much is a handful then

Depends on the size of your hands

Anything more than a handful is a waste

While I understand the logic, if the third graders didn’t know this how were they supposed to answer?

I hope you know I was talking out my ass when I said "cluster". I can also say
buttload
fuckton
assfull
bundle
group
clump
gathering
assortment
collection
