How many cubic feet are in 1 cubic yard

Have an understanding:

Cubic feet means the volume of a cube.

In a cube, the volume is calculated by multiplying the length, width, and height. The length, width, and height of a cube is the same. So, if the length is 2, then the volume would be 2x2x2=8.

1 yard = 3 feet.

If the cube is 1 cubic yard, then its length, width, and height are all 3 feet.

To find its volume, do 3 x 3 x 3 = 27.

The answer is 27 cubic feet.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
