Question

Expanding a garden. The dimensions are 25 feet by 25 feet. I bought 10 cubic yards of soil. How many inches thick will the new dirt cover

Answer 1

The thickness of the new dirt cover is 0.144 yards.

Explanation:

Dimension of garden = 25 feet by 25 feet.

Volume of soil bought = 10 cubic yards

Volume = length x width x height

But,

1 foot = 0.333333 yard

So that,

25 feet = 25 x 0.333333

= 8.33333 yards

The new dimension of the garden = 8.33333 yards by 8.33333 yards.

Let the thickness of the new dirt cover be represented by h.

Thus,

Volume = 8.33333 x 8.33333 x h

10 = 69.44439 x h

h =
`(10)/(69.44439)`

= 0.144

h = 0.144 yards

The thickness of the new dirt cover is 0.144 yards.
