We have several important things described in the statement
1. A concrete block weighs 2 ton
2. 1 ton= 1000kg
3. The truck maximum capacity is 8000 kg
We should determine how many concrete blocks the cart is carrying at its maximum capacity
First, let's determine in tons how much the truck can support
Now let's determine how many blocks can be carried in a maximum of 8 ton
the answer is that the truck can support 4 concrete blocks
