Answer:
i think the answer is thousands
The answer should be around 314.159. The formula is v=pi*r2*h. Plug in the numbers and its v=pi*25*4. That is 25*4 which is 100. Then *pi and it should be it.
Probability of a Die* rolling a 1 = 1/6
So you did it 36 times, ASSUMING it is a FAIR die, 1/6 * 36 = 6
You expect it to roll 6 1s
The fish box is 6 * 6 * 4 = 144 cubic square inches
144 = one box so divide 3456 by 144 to see how many boxes will go into the aquarium
3456 / 144 = 24
24 boxes of fish food could fit in the aquarium
