The perimeter of one of those six squares formed is 24 inches.

The rectangle measures 12 inches by 18 inches.

The rectangle is cut into six identical square by making three cut.

Therefore, let's find the area of the rectangle:

<h3>Area of a rectangle:</h3>
  • a = lw
  • a = 12 × 18 = 216 inches²

<h3>Area of a square:</h3>
  • a = l²

The square formed are 6 in numbers. Therefore,

6l² = 216

l² = 216 / 6

l = √36

l = 6 inches

The length of each square formed is 6 inches.

Therefore, the perimeter of each square formed is as follows;

  • 4l = 4(6) = 24 inches

If the surface area of the box of cereal is 272 inches squared, find the length of the box.
LekaFEV [45]

Answer:

x= 8 inches

Step-by-step explanation:

you left out the other lengths but since i had this same question once, the other lengths are 12 and 2-

dimensions of the box:

12 in x 2 in x ?

=272 square inches

and we know that there are 6 faces

area=  2 *(12 * 2) + 2 *(2*x) + 2 *(12*x)

area = 272 sq. in.  = 48 + 4x + 24x

272 = 48 + 28x

272 - 48 = 28x

224 = 28x

x = 8 inches

good luck :)

i hope this helps

brainliest would be highly appreciated

have a nice day!

9x+18+3x=1
Katen [24]
The error is in the second step they subtracted 3 from both sides but it was a 3x, which you can not do.
Correction.
9x+18+3x=1
12x+18=1
12x=-17
x=-17/12
