Question 854965
The volume of the first prism/container was
{{{length*width*height}}} ,
but there is no need to multiply the numbers given.
Anna doubled length, width, and height to build the second prism/container.
The volume of the second prism is
{{{(2length)*(2width)(2height) =2*2*2*length*width*height =8*length*width*height}}} ,
so the second prism's volume is {{{8}}} times larger.
 
When a figure or a solid is enlarged by a factor {{{k}}} (conserving shape and proportions),
the volume increases by a factor {{{k^3=k*k*k}}} ,
and the surface increases by {{{k^2=k*k}}} .
