Calculate the total weight of a pallet with 6 cartons per layer, 4 layers, each carton weighing 10kg, plus the pallet weight of 15kg.

To calculate the total weight of the pallet, you first need to find the weight of the cartons and then add the weight of the pallet itself.

Start by calculating the weight of the cartons. You have 6 cartons per layer, and there are 4 layers. So, the total number of cartons is:

6 cartons/layer × 4 layers = 24 cartons.

Next, since each carton weighs 10 kg, the total weight of the cartons is:

24 cartons × 10 kg/carton = 240 kg.

Now, you also have to account for the weight of the pallet, which is given as 15 kg. To find the total weight, you simply add the weight of the cartons to the weight of the pallet:

240 kg (weight of cartons) + 15 kg (weight of the pallet) = 255 kg.

Thus, the total weight of the pallet with the cartons is correctly calculated as 255 kg. This aligns perfectly with the correct answer choice provided.
