Question

Practice 2:

Babreka (The Kidney) is a lake in the Rila mountains, Bulgaria with the shape of a kidney. Its area is 85000m², and the average depth is 28m. Estimate the volume of the water in the lake in m³. Enter your solution without units below.

A. 2380000 m³
B. 238000 m³
C. 23800 m³
D. 2380 m³

Answer 1

The estimated volume of water in Babreka Lake is found by multiplying the surface area (85,000 m²) by the average depth (28 m), which equals 2,380,000 m³, corresponding to option B.

Step-by-step explanation:

To estimate the volume of the water in Babreka Lake, we can use the formula for the volume of a prism-like shape, which is the product of the surface area (A) and the average depth (h). The given surface area is 85,000 m² and the average depth is 28 m. To find the volume, we multiply the two:

V = A × h = 85,000 m² × 28 m

Calculating this we get:

V = 2,380,000 m³

So, the estimated volume of the water in Babreka Lake in the Rila mountains is 2,380,000 m³, which corresponds to option B.
