Hello, in this video i will be explaining the following.
00:03
So each section has an area of 50 times 50 divided by 2, which is 1 to 50 square feet.
00:17
So that's the area of each section.
00:20
Next we find the average elevation of each section.
00:24
So average elevation.
00:26
So we do 98 .67 plus 96 divided by 2, which is 97 .335.
00:42
So for the second section, this is for the first one, for the second section, average elevation, we would just do 92 .33 plus 95 .25.
01:04
Divided by 2 and that is 93 .79.
01:14
So next we find the difference in elevation.
01:17
So we just do 97 .335 minus 96 minus.
01:28
So that's 1 .335.
01:31
And then for the second one, we do 96 minus 93 .79.
01:37
And that is 2 .21.
01:39
So next we find the volume of the cut and fill.
01:47
Volume.
01:51
And the first one is going to be 1250 square feet times 1 .335, which is negative 1668.
02:07
Oh, not times.
02:11
We're subtracting.
02:14
Oh, we're multiplying.
02:16
We're multiplying by negative...
