#"Our aim is to find the value of"# #x#

#"As we know that the volume of the box (cuboid) is"# #18,# #"we can plug it into the equation"#

#color(blue)("Volume of cuboid"# #color(blue)(=l*w*h#

#"Where,"#

#color(red)("l is the length"=4#

#color(red)("w is the width"=x#

#color(red)("h is the height"=3#

#:.4*x*3=18#

#rarr12*x=18#

#rarrx=18/12#

#color(green)(rArrx=1.5#
