Volume of one room = Length × Width × Height
Volume of one room = 14 ft × 11 ft × 8 ft
Volume of one room = 1232 ft³
Total volume of water flooding the area = Volume of one room × Number of rooms
Total volume of water flooding the area = 1232 ft³ × 3
Total volume of water flooding the area = 3696 ft³

Volume = Weight / Weight per cubic inch
Volume = 91 pounds / 0.28 pounds per cubic inch
Volume 325 cubic inches
Length = Volume / Cross-sectional area
Length = 325 cubic inches / 5 square inches
Length 65 inches

Victoria is moving an iron pyramid with an octagonal base. the pyramid is 18 inches high and it's base has an area of 13.5 square inches. If each cubic inch of iron weighs 0.28 pounds the pyramid weigh 22.68 pounds.

Solution:
1. Flipping a coin and getting heads:
Assuming the coin is fair (unbiased), the probability of getting heads is 1/2.

2. Drawing an ace from a standard poker deck:
In a standard deck of 52 cards, there are 4 aces. So, the probability of drawing an ace is 4/52, which simplifies to 1/13.

3. Rolling 2 dice and getting a sum of either 7 or 11:
To get a sum of 7, there are 6 possible combinations of dice rolls: (1, 6), (2, 5), (3, 4), (4, 3), (5, 2), and (6, 1). To get a sum of 11, there are 2 possible combinations: (5, 6) and (6, 5).

The total number of possible outcomes when rolling 2 dice is 6 * 6 = 36.

So, the probability of getting a sum of 7 is 6/36, which simplifies to 1/6.
The probability of getting a sum of 11 is 2/36, which simplifies to 1/18.

Now, let's calculate the overall probability by multiplying the individual probabilities:

Probability = Probability of heads * Probability of drawing an ace * Probability of getting a sum of 7 or 11
Probability = (1/2) * (1/13) * (1/6 + 1/18)
Probability = (1/2) * (1/13) * (4/18)
Probability = (1/2) * (1/13) * (2/9)
Probability = 1/117

So, the probability of flipping a coin and getting heads, drawing an ace from a standard poker deck, and rolling 2 dice and getting a sum of either 7 or 11 is 1/117 or approximately 0.0085 (rounded to four decimal places).
