How many yards of topsoil do you need for a flower bed 104 inches by 144 inches by 12 inches?

Answer 1

I could just tell you, but it would be better if you knew how to figure it out. So I'll do both.

A cubic yard is equal to 27 cubic feet ( 3 x 3 x 3 feet ).

or 46,656 cubic inches.

Your garden is 104 x 144 x 12 inches or 8-2/3 x 12 x 1 feet.

( Let's stick with feet and eliminate one conversion! )

8-2/3 x 12 x 1 = 104 cubic feet.

Taking your measurement and dividing it by the number of cubic feet in a cubic yard gives us -

104 / 27 = 3.85 cubic yards

Call it 4 cubic yards to fill any little imperfections and you're good to go.

Answer 2

12 feet = 4 yards

8 inches = .2222 yards (8inches/36inches)

4 yards x 4 yards x 0.22222 yards = 3.5555 yards
