Question

A cell phone telecommunication tower stands in the shape of a rectangular pyramid. The tower stands 80 m tall and rests on a base that is 15 m by 20 m. What is the volume of the tower????
1. 24,000 m3
2. 8,000 m3
3. 12,000 m3
4. 70 m3

Answer 1

are you sure that right ????

Answer 2

are you really sure???

Answer 3

The volume of a rectangular pyramid is given by the formula V = (1/3) * base area * height.

First, we calculate the base area: base area = length * width
Base area = 20m * 15m = 300m^2

Now, plug in the values into the formula:
V = (1/3) * 300m^2 * 80m
V = 8,000 m^3

Therefore, the volume of the tower is 8,000 m^3.

Option 2 is correct: 8,000 m3.

Answer 4

Let's recalculate to confirm:

The volume of a rectangular pyramid is given by the formula V = (1/3) * base area * height.

Base area = length * width = 20m * 15m = 300m^2

Now, plug in the values into the formula:
V = (1/3) * 300m^2 * 80m
V = 8,000 m^3

After recalculating, we can confirm that the volume of the tower is indeed 8,000 m^3.

So, option 2: 8,000 m^3 is the correct answer.

Answer 5

Let's reexamine the calculations to ensure accuracy:

Given:
Height (h) = 80 m
Base length (l) = 20 m
Base width (w) = 15 m

The volume of a rectangular pyramid is given by:
V = (1/3) * base area * height

First, calculate the base area:
Base area = l * w = 20m * 15m = 300 m²

Now, plug in the values into the formula:
V = (1/3) * 300m² * 80m
V = (1/3) * 24000 m³
V = 8000 m³

Yes, after recalculating, the volume of the tower is indeed:
8,000 m³

Therefore, the correct answer is indeed option 2: 8,000 m³.
