How much mud (measured in liters) is there in a rectangular hole 2 meters wide, 3 meters long, and 3 meters deep?_______________________________ 2. What two two-digit numbers are each equal to their right-most digit squared?______________________ 3. Each of the following words contains the letters NOV (There may be more than one of each of those letters, but they are not shown.) ______________________ Using the definitions, fill in the words. _____________ A dispute or argument: _ _ N _ _ OV_ _ _ _.________ An astronomical feature: _ _ _ _ _ NOV_.__________ New or original: _ _ NOV_ _ _ _ _._______________ 4. What special quality does this limerick possess?_____ When an expert burlesque queen named Maizy, _____ Stripping velvet, became very lazy,______________ She would quickly exhibit just one jeweled explicit,__ Gliding off from the jokesters like crazy.__________ There, that should keep you busy for a while.________ And sorry for the lines, my layout is acting weird.
