How many cubic feet will it take to cover 625 square feet 2 inch thick?

Answer 1

First are you sure you want cubic feet and not cubic YARDS!

Where I sell/buy my stuff to they measure in cubic YARDS

the formula is CUBIC YARDS = (square feet) x (height inches) x .0031

in your case 625 x 2 x 0.0031= 3.9 cubic yards

Simple School Word math problem solving helps with cubic feet!

You gave the Square feet of the garden = 625.

The formula for Square feet is: length × width

The formula for Cubic feet is: length × width × height

First! All the measurements in formulas must be in the same units!

Convert the 2 inches to feet. The math formula is (part) / (whole )

we are using inches so just to remember show them in our formula

Formula is now (part in inches) / (whole in inches)

There are 12 inches in 1 feet . Our answer will be in Feet

So (whole part) in inches is 12 inches or 1 feet.

You have a 2 inches part OF the whole 12 inchesor 2 inches OF 12 inches

2 inches is 2/12 of a feetor 2 / 12 height in feet

Now sub into the Cubic feet formula all our know values

(cubic feet formula) = (square feet) × (height in feet)

(cubic feet) = (625 sq feet ) x (2/12 feet)

Doing the math using order of operations rules PEMDAS

we see P () the 2/12 feet reduces to 0.1666 feet as a decimal

Now (cubic feet) = (625) x (0.1666)

(cubic feet) = 104.125

You would need 104 cubic feet of topsoil.
