Problem Analysis

To solve this problem, we need to find the total number of liters of paint purchased. We are given that 12 three-liter cans and 6 five-liter cans of paint were bought. We need to calculate the total amount of paint in liters.

Solution

To find the total number of liters of paint purchased, we can add the quantities of paint from the three-liter cans and the five-liter cans.

Let's denote the number of three-liter cans as x and the number of five-liter cans as y.

The total number of liters of paint purchased can be calculated using the following expression:

Total liters of paint = (3 liters/can * x cans) + (5 liters/can * y cans)

Substituting the given values, we have:

Total liters of paint = (3 liters/can * 12 cans) + (5 liters/can * 6 cans)

Simplifying the expression:

Total liters of paint = 36 liters + 30 liters

Adding the quantities:

Total liters of paint = 66 liters

Therefore, 66 liters of paint were purchased.

Answer

The total number of liters of paint purchased is 66 liters.
