The radius of each gold medal = 3 inches.
Therefore, diameter of each gold medal = 2 × 3 = 6 inches.
The box is obviously in the rectangular form where
length => 6x4 = 12 inches
width=> 6x3 = 18 inches
The red tape fits snugly around the sides of the box,
so it will cover whole of the box.
Therefore, the length of the tape = 24+18+24+18 = 84 inches.
