Answer:
6m³ + 8m² + 12m
Explanation:
With box, you would draw a box with dimensions 1 x 3. In the outer edge of the 1 side, you would put 2m. In the 3, you would put 3m², then 4m, then 6.
Multiply in the boxes and add total.
Then for standard, you would do
2m(3m² + 4m + 6) = 2m(3m²) + 2m(4m) + 2m(6) =
6m³ + 8m² + 12m
Hope this helps! :)
