4 x 6 x .75 = 18 cu ft of sand
As you did not specify a depth, I can not provide an answer.
9.26 cubic yards for every inch of depth.
use a known volume container to measure a quantity = 200 x (the depth you want the sand).
how much 1" rock will I need to fill in a hole 20' long, 2' wide' and about 2' deep
100m3
72 cubic feet
32 cubic ft.
It will take 72 sq. ft. of sand. Or 2.66 sq. yds. That will fill the box even.
All you have to do is find the maximum volume of your sandbox. To do this, multiply the length (6 ft.) by the width (6 ft.) by the depth (10 ft.). 6 x 6 x 10 = 360 cubic feet This is if you want to fill the sandbox to the brim. If you want something about half the depth so that the sand isn't falling out everywhere, you just multiply: 6 x 6 x 5 = 180 cubic feet

Volume of sand required = 7 ft * 7 ft * 1/6 ft = 49/6 cubic feet = 8.166... cubic ft.
The answer will depend on the depth to which the area is covered.
15 * 5 * 0.5 = 37.5 cu ft. or 1.39 cu yards.
5300 gallons
(3 x 2 x depth of the hole in feet) cubic feet
12.5 cubic feet
Depends on the depth of the pool
