Pls Help me ASAP As a birthday gift, Albert made a wooden box to hold his younger sister's seashell collection.
The box is shaped like a cube and is 7.5 inches along each edge.
Which equation can you use to find the volume of the box, V?

7.5.7.5.7.5 = V

V = 3.7.5

What is the volume of the box?
Write your answer as a whole number or decimal. Do not round,

cubic inches:

but there’s no any figure there!

the first option i believe

step-by-step explanation:

do it yourself this is easy

step-by-step explanation:

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain
