Estimate in context by rounding

Problem

One full water bottle holds \(0.73~\text{liters}\). Estimate the total amount of water in \(6~\text{full}~\text{bottles}\) by first rounding \(0.73\) to the nearest tenth and then multiplying. Write the estimated total produced by this method, not the exact product.

4.38 liters; 6 × 0.73 = 4.38.

About 4.2 liters; 0.73 rounds to 0.7, and 6 × 0.7 = 4.2.

About 6 liters; 0.73 rounds to 1, and 6 × 1 = 6.

43.8 liters; 6 × 0.73 = 43.8.
