Answer:
Step-by-step explanation:
Use the Pythagorean Theorem.
base² + height² = hypotenuse²
6² + 8² = hypotenuse²
100 = hypotenuse²
hypotenuse = √100 = 10 meters
400/20
20m/s

This is a proportion question. We can express this as an equation where the answer is
x:
![\frac{1}{250}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B250%7D%20)
=
![\frac{x}{378}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7B378%7D%20)
From there, you can just cross-multiply and divide to get:
![\frac{1 * 378}{250}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%20%2A%20378%7D%7B250%7D%20)
A tenth of 250 is 25, so this is roughly
![\frac{375}{250}](https://tex.z-dn.net/?f=%20%5Cfrac%7B375%7D%7B250%7D%20)
or
![\frac{17}{10}](https://tex.z-dn.net/?f=%20%5Cfrac%7B17%7D%7B10%7D%20)
, so it'll be approximately 1.7 inches on the map.
Umm, surface area of a cube = 6e^2 (six edge square) which is 6(3)sqaure = 54
