3-35.

^{−3} kilograms and has a 1.5 × 10^{−1} meter wingspan. A giant golden-crowned flying fox bat, on the other hand, typically weighs 1.6 kilograms and has a wingspan of up to 1.7 meters. Estimate about how many times heavier a flying fox bat is than a bumblebee bat, without using a calculator. Homework Help ✎

Is the question about the mass (in kilograms) or the wingspan (in meters)?

This is about the mass (in kilograms).

So set up a ratio of the mass of the flying fox to the bumblebee bat.
