A wooden crate in the shape of a cube has a volume of 1

ladessa [460]

ANSWER

B. 8

EXPLANATION

Volume of wooden crate is

$\frac{1}{27} {ft}^{3}$

The cubic blocks have side length,

$l = \frac{1}{6} ft$

The volume of each cubic blocks is,

$v = {l}^{3}$

$= ( \frac{1}{6} )^{3} = \frac{1}{216}$

Number of blocks that can go into the crate is,

$= \frac{ \frac{1}{27} }{ \frac{1}{216} }$

$= \frac{1}{27} \times \frac{216}{1}$

$= 8 \: blocks$
