729-243=486
486×3=1458
1458+729=2187(x=7)
1458×3=4374
4374+2187=6561(x=8)
4374×3=13122(average rate of change for interval 8 to 9)
13122+6561=19683(x=9)

Step-by-step explanation:
Number of boxes that will fit =2340
Step-by-step explanation:
The shipping box volume can be calculated by the formula V = Lxwxh ,where L ,w ,h are length ,width and height of the box.
The length of the shipping box =3\frac{3}{4} =\frac{15}{4} ft.
Width = 3 ft.
Height =3\frac{1}{4} =\frac{13}{4} ft.
Volume of shipping box =\frac{15}{4} .3 .\frac{13}{4} =\frac{585}{16} = 36.6 ft.cubic ft.
Volume of shipping box can also be calculated by multiplying base area with the height of box.
Base area of box = \frac{15}{4} .3=\frac{45}{4} square ft.
Volume of box = base area x height =\frac{45}{4} .\frac{13}{4} = 36.6 cubic ft.
Volume of packing cubes =\frac{1}{4} .\frac{1}{4} .\frac{1}{4} =\frac{1}{64} cubic ft.
Number of fish boxes that will fit in the shipping box = volume of shipping box ÷ volume of fish food box = 36.6 ÷ \frac{1}{64} =2340 .
