15 POINTS FOR FULL ANSWER

6 ft

Step-by-step explanation:

Volume of a prism:

= base area×height

Using pythagoras theorem, find the length (let's call it t) of the other leg of the triangle (base)

17² = 8² + t²

289 = 64 + t²

t² = 225

t = 15 ft

Volume = Base area × height

360 = (½×8×15)×x

360 = 60x

x = 6 ft

55

step-by-step explanation:

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17
