Ab = Area of the base = 20 × 20 = 400 cm²

h = height = 26 cm

so, yoi have: (400 × 26) / 3

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
