The surface area of a cube is the combined area of all of its faces. The faces of a cube are squares, so to find the area of one face, we simply need to multiply the side length, which is 20, by itself.
20 * 20 = 400
So one face has an area of 400 units squared. To find the surface area, we just need to add all of the individual areas together. Cubes have 6 faces, so we can just multiply 400 by the amount of faces there are.
400 * 6 = 2400
The net, when folded into a cube, has a surface area of 2,400 units squared.

Answer:
inequality is
727.29-248.50+x>500
x=how much she needs to deposit
478.79+x>500
subtract 478.79 from both sides
x>21.21
at least $21.21
Step-by-step explanation:
product is multiplication so find the square root of 182
sqrt(182) = 13.49
so use the whole number above and below that
13 * 14 = 182
the page numbers are 13 & 14
Answer:
The rate of change in -4
Step-by-step explanation:
The rate of change is also known as the slope
To do this, take two points {(-2, 17) , (-1, 13)} and find the slope
m = slope
m = change in y/change in x
m = 13 - 17/-1 - (-2)
m = -4/1
m = -4
The rate of change in -4
The answer to your problem is 360
