3.2x1000=3200
And that's your answer: 3200
Hope this helps :)
Depends on how u look at the data and how the data is drawn out
1. 
is the area under the curve to the left of 
, which is a trapezoid with "bases" of length 2 and 5 and "height" 0.2, so
2. Find the area under the curve for each of the specified intervals:
(triangle with base 2 and height 0.2)
(triangle with base 1 and height 0.4)
(trapezoid with "bases" 0.2 and 0.4 and "height" 2)
(trapezoid with "bases" 0.1 and 0.3 and "height" 2)
Take out common numbers/variables in both terms;
6x(x³-27)
Hope I helped :)
