The longest blue whale on record was about 18 scuba divers in length. Use breaking apart to estimate the length of the blue whale. Explain how to estimate the length of the whale using compensation

The length of the blue whale in meters is 29.79 meters.

Length of the blue whale estimation: 108 ft

Step-by-step explanation:

Assuming that each scuba diver is 6 ft long, then the length of the blue whale is: 18 x 6 ft

This multiplication can be done using compensation as follows:

first, substitute 18 by 20: 20 x 6 = 120

then, adjust subtracting 6 groups of 2, or 12: 120 - 12 = 108
