Help with Math Problem, it's hard & confusing?

to make life a little easier, I would find AREAS first {big area minus little area)

^^^ you probably need to do this by partial pieces - which you add together

because then you know you multiply by .6cm (thickness aka height) and then by 1000 units.

Pick realistic measurements that are easy to deal with

use graph paper to see if your answers are close, if necessary

First a Area= sqrt(3)/4 a^2 so volume on 1000 pcs 600cm thick slice each to .6 cm this is a equilateral triangle.

b is 2 equilateral triangles so sqrt(3)/2 a^2

c I would make a sqare side length rstu.

Ok without actual sides and such not really able to give detail. I dont know how to help more

You need to find the volume of the entire object first and then subtract the volume of the inner shape. Volume is length (width)(height). In the problem it gives you the width as .6cm. Now you need 1000 of each one so you'll need to multiply your end result for one of them by 1000.

I hope this helped!
