Need to know the formula for find the perimeter. Need to solve this problem. A square metal box has a perimeter of 8.32". If the sides are .04" thick what is the perimeter of the inside?

8.32"+.04"x4

.o4x4=.16

0.16+8.32=

To find the perimeter of the inside of the square metal box, we first need to determine the length of each side of the inside square.

Given that the box has a perimeter of 8.32" and the sides are 0.04" thick, we can calculate the total thickness of all four sides using the formula:

Total thickness = 4 * side thickness

Total thickness = 4 * 0.04" = 0.16"

To find the length of each side of the inside square, subtract the total thickness from the total perimeter of the outside square:

Inside side length = Outside perimeter - Total thickness

Inside side length = 8.32" - 0.16" = 8.16"

Finally, the perimeter of the inside square can be calculated by multiplying the inside side length by 4 (since all sides of a square are equal in length):

Perimeter of the inside square = 4 * Inside side length

Perimeter of the inside square = 4 * 8.16" = 32.64"

Therefore, the perimeter of the inside of the square metal box is 32.64".
