The height of the above-water part of the iceberg is 30 m, which is one eighth

The height of the above-water part of the iceberg is 30 m, which is one eighth of its entire height. How deep does an iceberg go under water?

To solve this problem, we introduce the conditional variable “X”, through which we denote the depth to which the iceberg goes under the water.

Then, based on the data of the problem, we will compose the following proportion: 1/8 of the iceberg refers to 30 meters as 7/8 of the iceberg refers to X meters.

Then, based on this proportion, we make the following equation: X x 1/8 = 7/8 x 30.

Solving this equation, we get X equal to 210 meters.

Answer: the depth to which the iceberg goes under the water is 210 meters.
