This one is very easy, did you try it?



V = lwh  -->  w = V / (lh)     plug in for V, l, and h, and compute.



Just remember that because the volume is in m^3,  and l and h are given in ft, so you need to convert l and h to meters first, and your computed value of w will then be in meters.  (1ft  is about 0.3048m).  





In case you are new to Algebra...



Details/derivation:

V = lwh



Divide both sides by "lh":

V/(lh) = (lwh)/(lh)



Cancel "lh" on RHS:

V/(lh) = w



Re-write in standard form (swap LHS with RHS):

w = V/(lh)
