Sin 28 = 3/AB
AB= 3/ sin 28
AB=6.4
Given that the cube has a length given by 4/5n inches, the volume will be given by:
volume=length*width*height
but since it's a cube:
length=width=height
volume=(4/5n)^3
=64/125n^3 cubic inches
This is hard to solve when we don't know the visual graph this question is trying to refer from
The value is 21 Because three represents those to variables which both equal to 21.
I think the answer would be 7.5 hours or 4 hours,not so sure which one exactly
