below.
landing
what will be the length of the railing from
point a to point b? show or explain how you got
your answer.

Alright mate, lets do some math!
We are trying to find the height of each hay bale right? So we need to divide the volume by the length and the width... so:
H = (10 2/3ft^3) diveded by (1 1/3ft x 4ft)
H = 2 ft
There are 8 bales of hay mate, so we have to multipy that by the H... so 2x8= 16ft.
Hope this helped!
