# The Canmore Mining Company produces 40 tons of ore in an 8-hour shift. The mine operates continuously—3 shifts per day, 7 days per week. How many tons of ore can be extracted in 6 weeks?

To determine

To calculate: How many tons of ore can be extracted in 6 weeks, if company produces 40 ton of ore in an 8-hour shift and there are 3 shifts per day, 7 days a week.

Explanation

Given Information:

The company produces 40-ton ore in 8 hour shift.

There are 3 shifts per day.

The company works 7 days a week.

Formula used:

Steps for multiplying whole numbers.

Step 1: Write down the factors such that the place values line up in columns.

Step 2: Multiply every digit of the multiplier with the multiplicand, starting with the units. Each multiplication gives a partial product whose unit digit appears under the same column that is the corresponding digit of the multiplier.

Step 3: Now in each column, add the digits of the partial products, starting with the unit’s column on the right.

Calculation:

Consider the provided data,

The company produces 40-ton ore in 8-hour shift.

There are 3 shifts per day.

Therefore, total ore produced in a day will be,

40×    3        ¯

Multiply the multiplier ‘3’ with the multiplicand.

40×    3  120 ¯

120 tons are produced in 1 day,

The company works 7 days a week
