Which is taller: a 12-level vaulting box or a person who is 170 centimeters tall?

See the answer
female
In anglerfish, females are notably much larger than males, with bodies far bigger than those of the males. Females can grow to about 30–50 centimeters, whereas males are only around 5 centimeters. Because they live in the deep sea, males spend their lives attached to a much larger female, receiving nutrients from her to survive. This lifestyle is known as sexual dimorphism and is a unique characteristic of anglerfish.
Which is larger, a volleyball or a medium-sized pizza?
