To find the surface are youd have to multiply 6 1/2 by 6, because a cube has 6 total sides. so the answer would be 6•6.5 which equals 39

The formula of the surface area of the cube is 6s^2. “S” stands for side length, and you square it to get the area of one side of the cube. Multiply that by 6 (6 identical faces on a cube) to get the answer. So 6 x (6.5 x 6.5) equals 253.5 or 253 1/2. Don’t forget units if the problem has included them.

(-w-6)/(w^2+4w-12), how do i write this into simplest form?

PIT_PIT [208]

First factorise the top = -(w+6)
The first factorise the bottom: (w^2 + 4w -12) = (w+6) (w-2)
Therefore the two (w+6) cancels out and you are left with -1 / w-2

<h3>What is the unitary method?</h3>

A fundamental idea behind the unitary method is using the value of one unit to determine the values of additional units. Study up on the unitary method. With an increase in units, the value of additional units rises.

<h3>What is unitary set?</h3>

The general unitary group, also known as the group of unitary similitudes, is simply the product of the unitary group and the group of all positive multiples of the identity matrix. It includes all matrices A such that AA is a nonzero multiple of the identity matrix.

According to the question:-

The no: of pages needed for 6 letters = 6

The no: of pages needed for the other 6 letters= 6*2

=12

Total no: of pages are 18

Hence, the total no: of pages are 18
