well when you compare the linear measurements the ratio is 

46/92   of 1/2 

then the volume will be 

$$V  = (1/2)^3 \times 240 $$

campbell_st · Answer

the reason the scaling factor is cubed is because it's 3 dimensional

if it was area it would be squared.... 2 dimensions... 

hope it helps
