If the number is a multiple of 8, it is divisible by 8.
The multiples of 8 are: 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88... etc.
If a number is very big, let's say 176, see if you can deduct 80 from it. For this, 176 can be deducted by 80 twice, which will give you a remainder of 16 (I.e. 176 - 80 - 80 = 16". If this remainder (i.e. 16) is divisible by 8, 176 is divisible by 8.
For even larger numbers, try deducting 800, or even 8000.
Let's say you're trying to see if 2464 is divisible by 8. In this case, 2464 can be deducted by 800 thrice (I.e. 2464 - 800 - 800 - 800 = 64), and 64 is its remainder. Since 64 is divisible by 8, 2464 is divisible by 8.

Well, there are no weights mentioned, but 1/8 * 6 is 3/4. You can multiply this by the weight of the gravel.
Whatever that person said lol
0.66 inches of material is needed to be cut off to make the volume maximum.
<h3>maximum and minimum points test</h3>
When the second derivative of a function is negative, the function has a maximum point and if the second derivative is positive, the function has a minimum point.
Analysis:
After cut and folded, length = 8-2x
Width = 3-2x
Thickness = x.
Volume of the folded shape = (8-2x)(3-2x)(x)
After expansion, V = 4- +24x
for turning point of the function, dv/dx = 0
dv/dx = 12 -44x + 24
lowest term = 3 - 11x + 6
3 - 11x + 6 = 0
3 - 9x -2x +6 = 0
3x(x-3) -2(x-3) = 0
(3x-2)(x-3) = 0
x = 2/3 or x = 3
To test for maximum point, we differentiate dv/dx again
we have 6x - 11
for x = 3, 6(3) - 11 = 18 - 11 = 7 which is positive x= 3 is a minimum
for x = 2/3 6(2/3) - 11 = 4 - 11 = -7, x = 2/3 is a maximum.
Therefore for maximum volume, the length to be cut out is 2/3 which is 0.66 inches.
