Calculating the Total Number of White Paint Cans

To calculate the total number of white paint cans, we can use the given information about the green and white paint cans and their respective quantities.

Given: - Green paint: 60 kg per can - White paint: 120 kg per can - Total green paint cans: 15

Let's calculate the total number of white paint cans.

Solution:

1. Calculate the total weight of green paint: - Total weight of green paint = 60 kg/can * 15 cans

2. Calculate the total weight of white paint: - Total weight of white paint = 120 kg/can * x cans (where x is the total number of white paint cans)

3. Set up the equation: - Total weight of green paint + Total weight of white paint = Total weight of all paint

4. Solve for x (the total number of white paint cans).

Calculation:

- Total weight of green paint = 60 kg/can * 15 cans = 900 kg - Total weight of white paint = 120 kg/can * x cans = 120x kg

Setting up the equation: - 900 kg (green paint) + 120x kg (white paint) = Total weight of all paint

To find x: - 900 + 120x = Total weight of all paint

Result:

The total number of white paint cans (x) can be calculated using the equation 900 + 120x = Total weight of all paint.

Let's solve for x using the given information.
