Question

Soledad has a storage box. The box is 6 1/2 inches long, 4 3/4 inches wide, and 7 inches tall. She wants to run a border around the top of the box. How much border does she need?

Answer 1

The perimeter of the top is what is required; the 7 inch height is superfluous!

 

2(6 1/2 + 4 3/4) = 2[(13/2) + (19/4] = 2[(26/4) + (19/4)] = 90/4 = 22 1/2
