Substitute the given numbers into the given equation and solve for the unknown variable.
v=l*w*h
144 = l * 4 * 6
144 = l * 24
144 / 24 = l
l = 6 in

V =lwh solve for l
l=V/wh
l=144/4*6=144/24=6in

It's basic algebra. The formula is read "volume equals length times width times height", of course. Since you have the volume and the width and height, you divide the formula on both sides by w and h:
V = lwh
V/wh = lwh/wh
V/wh = l
Which means, take the total volume and divide that by the product of the width and height to find the length.

it means
144=4*6*l
l=144/24
l=6
