To calculate the total weight of the tins in the box, we first need to determine the total weight of the 25 tins, each weighing 250 grams.
-
Calculate the total weight in grams: \[ \text{Total weight in grams} = \text{Number of tins} \times \text{Weight of each tin} = 25 \times 250 , \text{g} = 6250 , \text{g} \]
-
Convert the total weight from grams to kilograms: \[ \text{Total weight in kg} = \frac{\text{Total weight in grams}}{1000} = \frac{6250 , \text{g}}{1000} = 6.25 , \text{kg} \]
Therefore, the total weight of the tins in the box is 6.25 kg.
