Answer:

4704 in²

Step-by-step explanation:

We are given that,

Edge of the cube = 6 in

We are asked to to find the surface area of the cube.

Surface area generally refers to total surface area .

$\bigstar \: \boxed{\sf {Surface \; Area_{(Cube)} = 6a^2 }} \\$

a denotes edge of the cube.

→ Surface area of cube = 6 × (28)² in²

→ Surface area of cube = 6 × 784 in²

→ Surface area of cube = 4704 in²

$\therefore$ Surface area of cube is 4704 in².

What is the greatest common factor of 20 and 30???

Ugo [173]

The greatest common factor of 20 and 30 is 10. This is because 10 is the largest number that when it is used to divide 20 or 30, it equals a whole number.

The simple way for us to solve is to write down the factors of both numbers, find the factors that match for both numbers, and see which is the largest out of those that match.

20: 1,2,4,5,10,20
30: 1,2,3,5,6,10,15,30

Using that logic, we can see that 10 is the greatest factor that the numbers share.
