For 30 blocks (6x5), you will need at least 37 light strips and 52 dark strips. For 36 blocks, you will need at least 43 light strip and 61 dark.
For a jelly roll with 40 strips of 2.5” by 42”, that means at least 3 jelly rolls. You will need even more if your jelly roll doesn’t have that many lights or if you want the quilt to be less scrappy. For example, if you want your largest piece 2.5 x 14.5 to be the same fabric, well, you can only get 2 from a 42” strip and thus would need 15 or 18 strips of the same fabric.

Welcome
Hello, neil. Welcome to the forum.
I think when you said 6x5 you mean 6 feet by 5 feet. Normally quilts are measured in inches, so 72 x 60. That is also regarded as a "Throw" size. I.e. not large enough to use as a bed spread.
6x5 could mean the number of blocks, and blocks vary in size.

if i found jelly rolls with all usable colors would this mean 2x40 strip rolls would be sufficient?

The number of strips indicated by suzSLO and IrishNY are close enough to make the size you want. Since most jellyrolls don't have equal numbers of light and dark you are wiser to buy rolls of all darker colors and rolls of all lighter colors. Depending on the strips in a roll will determine how many rolls to buy. Just get a few more strips than you think you need to be safe. Leftovers can always be used for binding. Good luck and have fun on your project.

Let me take a shot at this.
The total length of the dark colors in one block add up to 59.5". Multiply that by 36 blocks (6x6) = 2,142". Divide by 40" (average length of a jelly roll strip) = 54 strips of dark fabrics
Total length of light fabrics in one block add up to 45". Multiply by 36 = 1,620". Divide by 40" = 41 strips of light fabric.
Most jelly rolls (but not all) have 40 strips. You would need 3 jelly rolls BUT since you need a specific number of light and dark fabric strips, you'd have to carefully select rolls that have enough the right balance of light and dark strips, with enough variation in color to make the pattern. I suspect you might have to buy more than 3 jelly rolls to achieve that.
I hope this helps.

There is a good tutorial and pattern for a jelly roll pattern on the Jordan Fabric web site and it is free and it works perfectly. I used it in the picture below.
