Astorage company needs to design a new storage box that has twice the volume of its largest box. its
largest box is 5 ft long, 4 ft wide, and 3 ft high. the new box must be formed by increasing each
dimension by the same amount. find the increase in each dimension.

Since we know that length is twice the width, we can say that:
Perimiter = 2(twice the width) + 2(width)
Therefore, P = 2(2w) +2(w)
this simplifies to P=6w
Sine P=180, 160 = 6w, so w = 30
Because length is twice the width, length = 2 * width, or 2*30, which is 60

Therefore:
length = 60
width = 30
