I use one bag to 1 1/2 bags per hole and fill the rest of the way back with tamped topsoil... whatever came out of the hole.
No. You don't get an integer if you take the square root of 30. By way of example, 25 (5x5) is a square number, as is 36 (6x6).
How to know that you found all the factors for example my teacher taught me that when u reach a double diget number that is all the factors. ( 6x6)-~ double diget number
5x5=25 6x6=36 the only two prime numbers b/t 20 and 40 are 25 and 36
a square number is a multiplicatin problem that is the same for an example 6x6=36 because it makes a square a prime number is basicly a problem that has no multiplicatin problem except a 1 for an exsample 11x1=11
No. Square numbers are from numbers being squared like 2 squared is 4. Squaring a number is multiplying it by itself so 3x3=9, 4x4=16, 5x5=25, and so on. The closest square numbers to 40 are 36 (6x6) and 49 (7x7) there are no whole numbers to square in between 6 and 7 so 40 cannot be a square number
For a hole 36" deep X 18" diameter, you would need approx. 1/5 cu. yd. concrete.
Hundreds of pounds
No
36
6x6=36
36
6x6=36
That would depend on how big the addition was.
6x6 = 36
6x6 in standard form = 36
Tu doit avoir un deux pouce de rayon qui excaide une fois ton 6x6 à l'intérieure du sonotube(45degré de coin à coin 2" ext.)
around 39.99 or 40 since 5x5 products were 30
