13. A hole is drilled in a block of wood as shown in the sketch. The hole is 3/4 of

the total depth of the wood. The total depth of the block of wood is 13/16 in.

How deep is the hole?

Hole

Answer 1

The depth of hole is 0.609 inches.

Given, the total depth of the block of  wood is  $\frac{13}{16}$ inches.

Since the hole is $\frac{3}{4}$ of the total depth, so the depth of the hole will be,

$D=\frac{3}{4} \times\frac{13}{16}$

Or, $D=\frac{39}{64}$

$D=0.609375 \ in$

Hence the depth of hole is 0.609 inches.
