Answer:
17inches
Step-by-step explanation:
If James completely covered a square poster board using 68.2 in. of cardstock, this means that the perimeter of the square box is 68.2in.
To get the measurement if one side if the box we will use the formula for finding the perimeter of the square.
P = 4L
L is side length of the square box
68.2 = 4L
L = 68.2/4
L = 17.05in
.hence the measurement closest to one side of the square box is 17inches
