Answer 2

$\boxed {\mathfrak{Hello !!}}$

Given :- Volume of Cuboid :-

${3x}^{2} - 12x$

We all know that volume of Cuboid =

$l \times b \times h$

ACCORDING TO QUESTION

${3x}^{2} - 12x = l \times b \times h \\ \\ 3x( \: x - 4 \: ) \: l \times b \times h \\ \\ 3x \times x \: \times - 4 = l \times b \times h \\ \\l = 3x \\ \\ b = x \\ \\ h = - 4$

$\boxed {\mathfrak{Hope \: it \: helps \: u!!}}$
