A company uses cardbaord tubes to make concrete posts for the foundation of a building. If a building requires 35 tubes, what is the volume of the concrete required? d=.26 h=2.4
What is d/ 2 = .26 / 2 = .13 3.14 x .13x.13x2.4 V = .12736 Multiply by 35 because that is how many tubes you require. .12736 x 35 v = 5m3 of concrete.
