Two large cubes are made out of unit cubes. cube a is 2 by 2 by 2. cube b is 4 by 4 by 4. the side length of cube b is twice that of cube a. is the surface area of cube b also twice that of cube a? explain or show reasoning.

is the volume of cube b also twice that of cube a? explain or show reasoning.

The side length of Cube B is twice that of Cube A.

Surface area of Cube B is not twice that of Cube A.

Volume of Cube B is not twice that of Cube A.

Step-by-step explanation:

Cube A is 2×2×2.

Cube B is 4×4×4.

Side length of Cube A is 2 and side length of Cube B is 4. So, the side length of Cube B is twice that of Cube A.

Surface area of a cube is

Using this formula we get

96 is 4 times of 24. So, surface area of Cube B is not twice that of Cube A.

Volume of a cube is

Using this formula we get

64 is 8 times of 8. So, volume of Cube B is not twice that of Cube A.

step-by-step explanation:

bob the banana

an = 22 + (n-1) *6

110 seats

step-by-step explanation:

an=a1+(n-1)(d)

a1 = 22   this is the first item in the sequence

d =6   this is how the sequence goes up

a)   an = 22 + (n-1) *6

b) a12 = 22 + (12-1) *6

    a12 = 22+11*6

  a12 = 22 +88

  a12 = 110
