sizes for the base of the boxes.

box 1: the length is 3 times the width.

box 2: the length is 1 less than 4 times the width

width: x; length: 3

width: x; length: x + 3

width: x; length: x-3

width: x; length: 3x

step-by-step explanation:

*calories burned = (weight)(calorie factor)*

calories burned = 180 (0.65)

calories burned = 117

the calories he used up is 117, which is 65% of his weight.
