Okay, so now I have 5 cubic feet of drainage rock. What I need is about:

( ( 24' width/side x 2 sides ) + ( 28' length/side x 2 sides ) ) x 3' wide border x 1" thick border

= ( 48' + 56' ) x 3' x 1"

= 104' x 3' x 1"

= 312 square feet x 1/12 feet thick

= 26 cubic feet

Alternatively:

( ( 12' width/side x 2 sides ) + ( 14' length/side x 2 sides ) ) x 3' wide border x 1" thick border

= ( 24' + 28' ) x 3' x 1"

= 52' x 3' x 1"

= 156 square feet x 1/12 feet thick

= 13 cubic feet

Hopefully this will keep the ticks away. They also had some rubber mulch, for about the same price, but I didn't get any of that. https://www.lowes.com/pd/Rubberific-0-8-cu-ft-Dark-Brown-Rubber-Mulch/3199901

Okay, so each bag provides coverage over 3 square feet, to a depth of two inches.

What I need are:

( 20 x 2 x 3 ) + ( 12 x 2 x 3 ) square feet

= 120 + 72 square feet

= 192 square feet

That's 64 bags, or 32 cubic feet.

I used up my drainage rock, so now I gotta get more. I expect to buy 10 more bags of that on Monday, and then go out to the field that same day with some pruning shears, hedge shears, loppers, and a sickle. Maybe I should've gotten a machete, too, but oh well.
