Cuboid

How many times will increase the volume of a cuboid, if one dimension is twice larger, second dimension three times larger and third dimension four times lower?

Correct result:

n =  1.5

Solution:

$$\begin{gathered} V_1=abc \\ {V}_2=2a\cdot 3b\cdot c\mathrm{/}4=1.5abc=1.5V_1 \\ n=V_2\mathrm{/}{V}_1 \end{gathered}$$
