Let the length of the first piece be "x", second piece be "y" and third piece be "z".

Total length is 234 inches, so we can write:


x+y+z=234

Also,

• Second piece is 4 times the first piece, ,we can write:


y=4x

• Third piece is 8 times the first piece, ,we can write:


z=8x

Substituting these 2 equations into the first equation, we will have an equation in x. Then we solve for x. Shown below:


\begin{gathered} x+y+z=234 \\ x+4x+8x=234 \\ 13x=234 \\ x=18 \end{gathered}

Consequently, we can find y and z >>>>

y = 4x

y = 4(18)

y = 72

and

z = 8x

z = 8(18)

z = 144

Answer

First Piece = 18 inches

Second Piece = 72 inches

Third Piece = 144 inches
