Ihave 3 flower vases. my daughters sent me flowers. the packet of cut flower food that came with the flowers says to add 1/2 gallon of cool water. i want to fill the vase at least half before adding the flowers, but no more than 3/4 full before adding the flowers. (231 cubic inches = 1 gallon)

which vase would be best to use?

my vases are:

a cylinder with a diameter of 8" and 8" tall

a rectangular prism that is 4" by 5" and 10" tall

a triangular prism with a height of 10". the triangular base has a height of 6" and a base of 3"

which vase do i use? justify your answer.

The cylinder vase, I think, if you give me about five minutes I'll know for sure! I'm taking the test right now

Step-by-step explanation:

The volume of the rectangular prism is 200

Equation: length x width x height = 4 x 5 x 10 = 200

The volume of the cylinder is 402.12

Equation: = = 402.12

The volume of the triangular prism is 180

Equation: base area x height = (6 x 3) x 10 = 180

To evaluate this situation, you need to look at the given information. We know that b is 2.1 and that the expression b is put into is 8b-12. So, just plug in for b. 
8*2.1 - 12. Use the order of operations to ensure a correct answer. So, multiply first. 8 * 2.1 is 16.8. Nou, subtract. 16.8 - 12 = 4.8. So, the final answer is 4.8
