Answer:
Explanation:
In the diagram we can see 4 equal parts in circles, each contain:
- 2 cubes with side of 10, 1 square with side 10, 4 rectangles with sides 1 × 10.
Their sum of each circle is:
- 2 × (10*10*10) + 10*10 + 4 × (1*10) =
- 2000 + 100 + 40 =
- 2140 units
The total is:
The correct division model would be reverse operation:
Correct choice is A (considering the last digit is zero not 2).
