7120

To write this in standard form, move the decimal point the number of spaces that the ten is raised to (right is positive, left if negative).

Since this is raised to the power of 3, we are going to move the decimal point right 3 spaces and add zeros as placeholders if needed.

$7.12*10^3 = 7120$
