Step-by-step explanation:
Judging from the high of 400, her day 21 appears to be approx 300
if she put in 100 then the next five days she added a total of 200 more to reach 300
200/5 = $40 / day
A cube has all the sides equal.
A diagonal then acts as the hypotenuse of a face such that,
Sin 45° = Side/hypotenuse = Side/12.8 => Side = Hypotenuse * Sin 45 = 9.05 in
Volume = base*width*height = sides^3 (since all sides are equal) = 9.05^3 =741.22 in^3
To nearest tenth,
Volume = 741.2 in^3 {and correct answer is A)}
