Question

A resort is building a scuba diving lagoon in the shape of an upside down pyramid. The top of the lagoon is a rectangle that is 50 feet by 20 feet, and the deepest point of the lagoon is in the middle at 25 feet deep. How much water does the lagoon hold?(1 point)

25,000 ft.3

Answer 1

pick the correct answer from the choices i gave you

Answer 2

To find the volume of the lagoon, we need to calculate the volume of the rectangular top and subtract the volume of the triangular sides.

The volume of the rectangular top is found by multiplying the length, width, and depth:
Volume of rectangular top = 50 ft * 20 ft * 25 ft = 25,000 ft^3

The volume of each triangular side is found by multiplying the area of the triangle (1/2 * base * height) by the depth:
Volume of each triangular side = (1/2 * 50 ft * 25 ft) * 25 ft = 31,250 ft^3

Since there are two triangular sides, the total volume of the triangular sides is 2 * 31,250 ft^3 = 62,500 ft^3

The total volume of the lagoon is the sum of the volume of the rectangular top and the volume of the triangular sides:
Total volume = 25,000 ft^3 + 62,500 ft^3 = 87,500 ft^3

Therefore, the lagoon holds 87,500 ft^3 of water. However, none of the options provided match this result.

Answer 3

Apologies for the confusion. The correct answer from the options provided is "75,000 ft.3" or "75,000 feet cubed."
