0.3333333333... = 1/3
You can just say 0.3 repeating to say 0.33333...
3/8 + 1/8 = 4/8 = 1/2
The simplified answer is 1/2.
15.75=5(1+i)^2
3.15=1+i^2
2.15=i^2
i= √2.15 or approximately 1.47
Ok, so the bigger box has sides that are multiples of 4.5 inches:
18in * 9in * 4.5in.
in terms of the cubes that go inside them, the bigger box is:
4 box * 2 box * 1 box, so you know that 8 boxes fit inside.
