Compute the sum of the lengths of all the edges in a rectangular solid 5 by 4 by 3 inches.
What will be an ideal response?
The sum of the 4 edges on the top surface = (2 * 4) + (2 * 5) = 8 + 10 = 18 The sum of the 4 edges on the bottom surface is also 18
The sum of the 4 side edges is 3 + 3 + 3 + 3 = 12
Thus the sum of all 12 edges is 18 + 18 + 12
Sum of edges is 48 feet
