          A:  The PI x radius squared x height = volume is a good answer. But you don't need to line the entire hole with the tube. When the liquid concrete reaches the grade, you top it with a piece of tube cut to the right length above grade and fill inside the tube.

          by|Aug 12, 2023

            A:  pi x r squared x height= cubic volume.  It depend on how wide the tub is & how much you fill it. Please remember to compensate foe what ever you add to the tube 1st. ei sand or filler rock, etc…

              I used this to make a north pole decoration. It turned out beautiful and was a big hit at our party.

                This is a great Product
                I needed something sturdy like this for my son’s school’s trunk or treat. I signed up to make the canisters from Monsters Inc. I purchased one and was able to get them cut in half in order to get two. Worked perfectly for what I needed because I needed something with a bit of weight so it wouldn’t fall when placed on the floor.

                    Ideal Form Tube For Setting 4x4 Posts
                    This form tube is easy to use and helps to simplify the process of setting concrete for posts or columns. The manufacturer provides printed instructions on the outside of the tube form. Most important is that this form tube which is made of treated cardboard must be completely dry prior to concrete being poured into it for the tube form to maintain maximum strength and integrity. The manufacturer also specifies the amount of concrete mix required per foot on the outside of the form tube to fill the length of the form tube. The diameter of the form tube is +/- 0.5 inch to make it cheaper and easier to ship several form tubes by nesting them inside of each other. I used three 80 pound bags of concrete mix to fill all of the 48" length of this 8" diameter tube form and had some concrete left over. It is always better to have some concrete left over then it is to not have enough concrete because concrete must be mixed properly and poured all at once for all of the concrete to bond correctly as one solid mass before the concrete sets. The 8" diameter of this form tube is an ideal size for setting 4x4 posts since the Strong Tie post bases recommend 2" of concrete on all sides of their bases. 8" diameter is also just large enough to be able to use a spade shovel to compact the concrete as it is poured into the tube form.

                        It worked perfectly for what I was doing. Easy to cut down to the size I needed to help support fence post that I was repairing.

                          TUBE DIAMETER IS NOT CONSISTENT WITH THE 8" SIZE
                          by
                          Response from Sakrete Customer CareNov 29, 2023
                          - Home Depot Customer, this is considered nesting. Typically, this is done with three tubes. The reason all 3 of these tubes meet the same diameter requirements is the industry allows for a +/- .5-in variance, with the intention to allow for nesting. Should you have any further questions or concerns, please contact us at 1-866-SAKRETE. sakrete
