Is an estimate of 28,000 over under the actual peoduct of 360 68? How can you tell

Over Estimate of the actual product.

Step-by-step explanation:

360*68 = 24,480

The estimate of 28,000 is larger than the actual product 360 and 68 which is 24480, which means that the estimate is an over estimate (an over estimate means that the number you estimated is bigger than the actual number, and an under estimate is when the estimate is smaller than the actual number, Just FYI)
