|  | # --description--
 | ||
|  | 
 | ||
|  | A firecracker explodes at a height of 100 m above level ground. It breaks into a large number of very small fragments, which move in every direction; all of them have the same initial velocity of 20 m/s. | ||
|  | 
 | ||
|  | We assume that the fragments move without air resistance, in a uniform gravitational field with g=9.81 m/s2. | ||
|  | 
 | ||
|  | Find the volume (in m3) of the region through which the fragments move before reaching the ground. Give your answer rounded to four decimal places. | ||
|  | 
 | ||
|  | # --hints--
 | ||
|  | 
 | ||
|  | `euler317()` should return 1856532.8455. | ||
|  | 
 | ||
|  | ```js | ||
|  | assert.strictEqual(euler317(), 1856532.8455); | ||
|  | ``` | ||
|  |

|  | ```js | ||
|  | function euler317() { | ||

|  |

|  | euler317(); | ||
