Question 155276
From the problem given, the {{{Rate}}} equals {{{time/volume}}}:
{{{1minute/(Length*Width*Height)}}}
{{{1/(3*3*3)=1minute/27in^3}}}
Remember: {{{Time=t}}} to eat the 6"L x 6"W x 6" H block:
{{{t/(6*6*6)=t/(216in^3)}}}
So we can equate the equations:
{{{1/27in^3=t/(216in^3)}}}, cross multiply
{{{t*27in^3=216in^3*1min}}} 
{{{t*cross(27in^3)/cross(27in^3)=cross(216in^3)8*1min/cross(27in^3)}}}
{{{t=8minutes}}}
Remember: The rate is time per volume of block
Thank you,
