Hello from MrBillDoesMath!

Answer: NO solution possible!

Steps:

Let "n" be the first even number. We are told that

n + (n+2) + (n+4) + (n+6) + (n +8) = 216

The third number, the value we want, is boldfaced above.

Simplify the above equation:

5n + ( 2 + 4 + 6 + 8 ) = 216 or

5n + 20 = 216 or

5n = 196

n = 196/5 is NOT an integer value. This problem, as stated, has no solution.

prohojiy [21]

Answer:

The length of each side of the polyhedron, s is 4.142 or

= $10(\sqrt{2}-1)$

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

$\sqrt{x^2 + x^2} = \sqrt{2x^2} =x\sqrt{2}$

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

$x = \frac{10}{\sqrt{2}+2 }$

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

$s = x\sqrt{2} = \frac{10}{\sqrt{2}+2 }\sqrt{2} = 10\sqrt{2} -10 = 10(\sqrt{2}-1) = 4.142$

The length of each side of the polyhedron, s = 4.142.
