You can put this solution on YOUR website!
a.) Volume of a cube with side s.
V=s%5E3=12%5E3=+1728
The box has 1728 cubic inches of volume.
.
.
.
b.) Length=15 (12+3),Height<12, Width is unspecified.
The volume for this box would be
V=L%2AH%2AW
V=15%2AH%2AW
1728=15%2AH%2AW
H%2AW=115.2
If H is less than 12, then
W%3E9.6
There is not enough information to complete the problem.
The height and width are allowed to vary, but should follow
H%2AW=115.2
to achieve the same volume as before.
Are the width and height supposed to be the same?
