Suppose we want to paint a cube so that there remains an unpainted stripe along all the edges on each face. The width of the stripe should be \( 1\,\mathrm{cm} \). The producer gives the paint consumption \( 100\,\mathrm{ml}/1\,\mathrm{m}^2 \). From the following functions choose the one that describes the dependence of the paint consumption \( V \) on the length of the cube edge \( a \). The paint consumption \( V \) is given in millilitres and the length of the cube edge \( a \) is given in meters.
\( V=\left(a-\frac1{50}\right)^2\cdot600 \)
\( V=\left(a-\frac1{50}\right)^2\cdot\frac3{50} \)
\( V=\left(a-\frac1{100}\right)^2\cdot600 \)
\( V=(a-2)^2\cdot100 \)
