To find the volume of a rectangular pyramid, you can use the formula:
\[ V = \frac{1}{3} \times \text{Base Area} \times \text{Height} \]
- Calculate the base area: The base of the pyramid is a rectangle with dimensions 15 m by 20 m.
\[ \text{Base Area} = \text{Length} \times \text{Width} = 15 , \text{m} \times 20 , \text{m} = 300 , \text{m}^2 \]
-
Use the height: The height of the pyramid is 80 m.
-
Calculate the volume:
\[ V = \frac{1}{3} \times 300 , \text{m}^2 \times 80 , \text{m} = \frac{1}{3} \times 24000 , \text{m}^3 = 8000 , \text{m}^3 \]
Therefore, the volume of the tower is 8,000 m³.
