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:
The 4 on the right is 10 times larger than the 4 on the left.
Step-by-step explanation:
In order to find this, we turn every number in the term into a 0 except for the 4.
4 on the right: 900441358 = 000400000 = 40,000
4 on the left: 900441358 = 000040000 = 4,000
Now that we have these two numbers, we can divide one by the other to find the relationship.
40,000/4,000 = 10
Therefore, the right one is 10 times as large as the left one.

Answer:
The amount of their mortgage loan is $108000
Step-by-step explanation:
we are given
total purchasing amount =$123000
down payment amount = $15000
we know that
Mortgage loan amount = (total purchasing amount)-(down payment amount)
now, we can plug value
Mortgage loan amount = $123000-$15000
Mortgage loan amount =$108000
