Answer:
3,200
Step-by-step explanation:
4000
3200 x 250 = 800,000 x 0.1 = 80,000
4000 x 250 = 1,000,000 x 0.1 = 100,000
4200 x 250 = 1,050,000 x 0.1 = 105,000
5000 x 250 = 1,250,000 x 0.1 = 125,000
36
There would be three on each edge. (Five, minus the two ends that have 3 sides painted.)
A cube has 12 edges.
12x3=36
