The formula is
V+=+L%2AW%2AH+
+V+ = volume
+L+ = the length
+W+ = the width
+H+ = the height
--------------------
You are given:
+V+=+160+ in3
+W+=+L+-+3%2A12+ in
+H+=+4+ in
( note I converted +3+ ft to inches )
--------------------
Plug data into formula and
find +L+ and +W+
-------------------------
This is possible because you have
2 equations and 2 unknowns
