Answer:
The length of each side of the polyhedron, s is 4.142 or
= 
Step-by-step explanation:
If we take the distance of the length of the side of the cube where Donatello make the cut to the corner of the cube as x we get the side of length each polyhedron as

x·√2 because we have an hy
Therefore, the original cube had sides of length
10 = 2·x + x·√2
Solving for x we get

Therefore the length of s is x·√2 which gives

The length of each side of the polyhedron, s = 4.142.
The volume of a cylinder can be found using the formula πr²h.
V = (3.14)(6)²(6)
V = 678.24 cm³
From the answer choices it will be:
V = π(6)²(6)
V = 216π cm³
So the answer is answer choice B.
Hope this helps :)
Answer:
The steps are more or less the same, except for one new addition:
1. Divide the tens column dividend by the divisor.
2. Multiply the divisor by the quotient in the tens place column.
3. Subtract the product from the divisor.
4. Bring down the dividend in the one's column and repeat it.
