Question

Determine the number of square feet in one square yard Then determine the number of cubic feet in a cubic yard.

Can anyone help me. I know that this is easy stuff, but I just can't think straight right now! PLEASE HELP!

Answer 1

Question 1
1 yd ² = 3 x 3 ft ² = 9 ft ²

Question 2
1 yd ³ = 3 x 3 x 3 ft ³ = 27 ft ³

Answer 2

First: the square yard. That means your trying to find the area of a square, and the formula for that is "area=length x width"

you know the length and width are both one yard, and one yard is 3 feet. So to find the square feet in one square yard you do:

area=3feet x 3feet =9square feet

so there are 9 square feet in a square yard.

Second: the cubic yard is essentially the same, except you use the formula for a volume of a cube:
"volume=length x width x height"

again: the length, width, and height are all one yard...which means they are all 3 feet (because one yard is 3 feet)
so the formula is:

volume=3feet x 3feet x 3feet=27 cubic feet

so there are 27 cubic feet in a cubic yard.

Answer 3

1 square yard = 9 square foot
1 cubic yard = 27 cubic foot

To convert any sort of units, you can use google. Just type the following in the search bar:

1 square yard in square feet.

This is how you get the answer to your particular problem; we know that:

1 yard = 3 feet . Square both sides and you have:
1 yard^2 = 3^2 feet^2 ==> 1 yard^2 = 9feet^2

Same goes for cube.

Answer 4

Draw a square. Imagine it's a yard by a yard - therefore three by three feet. Divide it up - nine squares - one square yard is nine square feet.

Stretch the imagination. Draw a 'three-d' picture of a cube. Imagine one-by-one-by-one yard -- three-by-three-by-three feet = 27 cubic feet.

Answer 5

Use dimensional analysis:

1 yd^2 * (3 ft / yd)^2 = 1 yd^2 * 9 ft * ft / (yd * yd) = 9ft^2

1 yd^3 * (3ft / yd)^3 = 1 yd^3 * 27 ft * ft * ft / (yd * yd * yd) = 27ft^3
