**Step-by-step explanation:**

I dont understand but here is a example how it may look like.

**Answer:**

6.913 cubic-meters/second.

**Step-by-step explanation:**

Volume of pyramid is.

and

we essentially need to compute derivative at h = 3.

but firs we need to write s in terms of h only, to do that we use the fact that ration of side to height of a pyramid is always constant, which means.

solving for s and substituting in Volume function gives.

and taking derivative with respect to time gives.

but we have been given that piece of information so.

at h = 3 in above we have finally.

**Answer:**

96 inch,180 inch,216 inch

**Step-by-step explanation:**

let the sides be 8x,15x,17x

then 8x+15x+17x=480

40x=480

4x=48

x=48/4=12

8x=8×12=96

15x=15×12=180

17x=17×12=216
