Answer:
Supposing the three boxes are in the shape of cuboid.
Area of base of each box = 16 square feet
Height of two boxes which are identical = 3 feet
Height of third box= 5 feet
Volume of Box = Area of Base × Height
Total Volume of three boxes = 16 × 3+16 ×3 +16 × 5
= 48 +48 +80
=96 +80
= 176 cubic feet

<h3>Answer: 5</h3>
=================================
Explanation:
Apply the difference of squares rule
x^2 - y^2 = (x-y)(x+y)
x^2 - y^2 = (5)(1)
x^2 - y^2 = 5
----------
Alternatively, you can solve the system
for x and y to get (x,y) = (3,-2).
Then compute x^2-y^2 = 3^2-(-2)^2 = 9-4 = 5
