Tim brought 128 sandbags to completely fill a cube-shaped sandbox. each bag fills a cubic foot in the sandbox. what is the length, in feet, of one of the sides of the sandbox?

i used to know how to do this in 7th but i forget easily

step-by-step explanation:

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

answer: graph 2
