My bill is 3 inches by 2 2/3 inches by 1/3 inch what is the volume of my bed

That should be 3 x 2.66 x .33 which equals 2.63 cubic inches

*This is what is easiest for me. I hope it helps you.*

1.) First I would turn the mixed fraction into an improper fraction. 2 2/3 turns into 8/3.

2.) I would get the fractions over with. So 8/3+1/3. Lucky you. You don't have to find the Least Common Factor. Add the numerators and you get 9/3.

3.) Next do 9 divide 3 and you get 3.

4.) 3•3 and you get back to 9.

5.) The volume of your bed would be 9 inches.
