Problema Solution
The height of a box Juan is building is 3 inches less than the width of the box. The length is 2 inches more than twice the width. The volume of the box is 1540in3. Which one is NOT a dimension of the box?
Answer provided by our tutors
let 'w' represent the width, then 'w-3' represents the height and '2w+2' represents the length
volume = height * length * width
1540 = w * (w-3) * (2w+2)
solving for 'w' we have w=10
10-3=7
2*10+2 = 22
the width of the box is 10 in, the height is 7 in and the length is 22 in
