Multiply 199 by 355 to give you 70,645. Then add 70,645 to 1068 to give you 71,713.
So using the conversion of 1 metric ton to kg, we see that there are 1000 kg in 1 ton. Then we can divide 40 by 1000 to find the decimal:

Then to convert this decimal to a percentage, we must multiply by 100%:

So now we know that 40 kg is 4% of 1 ton.
Sum of all exterior angles = 360°.
Number of sides = 360 ÷ 40 = 9
Each interior angle = 180 - 40 = 140°.
