Elena packed 48 cubes.
Each cube has an edge of 1 centimeter.
The number of layers that Elena can make depends on how each layer is arranged and depends on how many cubes are there in a layer.
Assume that each layer has only 1 cube, then there are 48 layers.

Answer:
![\frac{\sqrt{17} }{7}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%7B17%7D%20%7D%7B7%7D)
Step-by-step explanation:
Using the Pythagorean identity
sin²x + cos²x = 1, then
sinx = ![\sqrt{1-cos^2x}](https://tex.z-dn.net/?f=%5Csqrt%7B1-cos%5E2x%7D)
Note that (
)² = ![\frac{32}{49}](https://tex.z-dn.net/?f=%5Cfrac%7B32%7D%7B49%7D)
sinΘ = ![\sqrt{1-(32/49)}](https://tex.z-dn.net/?f=%5Csqrt%7B1-%2832%2F49%29%7D)
=
= ![\frac{\sqrt{17} }{7}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%7B17%7D%20%7D%7B7%7D)
If you're solving for a, you would add 32 to both sides
2a=32
then you would divide by 2
a=16
