A geologist collects 48 rock samples from the Himalayas and divides them equally into 6 containers. If 2 containers are sent for further testing and each sample is analyzed in 3 separate tests, how many total tests are conducted?

A growing interest in geology and material analysis has drawn attention to real-world scientific workflows—like how researchers manage large sample sets across multiple tests. This scenario reflects a common challenge in earth sciences: how to efficiently process vast quantities of natural materials. When a geologist begins with 48 rock samples collected from the Himalayas, dividing them equally among 6 containers ensures organized handling and streamlined testing. Sending 2 of these containers for in-depth analysis marks a critical step, followed by analyzing each individual sample across 3 distinct tests. This approach balances precision with practical lab workflow—optimizing both time and resource use.


Understanding the Context

Why This Scenario Matters in Current US Contexts
The geological analysis of Himalayan rock samples connects to wider conversations about natural resource mapping, climate research, and environmental science education. With increasing public interest in earth science—fueled by documentaries, educational platforms, and STEM trends—audiences track how scientists process data from remote, complex regions. The image of samples carefully organized in containers and tested systematically resonates with those curious about traceable, methodical scientific inquiry. It reflects a trend where complex, data-heavy fields become more accessible through relatable, real-world examples—especially when presented with factual clarity.


Calculating the Total Number of Tests

The core calculation centers on 48 total rock samples. These samples are split into 6 containers, meaning each contains 8 samples (48 ÷ 6 = 8). When 2 containers are selected for further analysis, that’s 2 × 8 = 16 samples entering the testing phase. Each of these 16 samples undergoes 3 separate tests, leading to a total of
