Total Volume of All Boxes

Given an array of boxes, create a function that returns the total volume of all those boxes combined together. A box is represented by an array with three elements: length, width and height.

For instance, totalVolume([2, 3, 2], [6, 6, 7], [1, 2, 1]) should return 266 since (2 x 3 x 2) + (6 x 6 x 7) + (1 x 2 x 1) = 12 + 252 + 2 = 266.

Examples

totalVolume([4, 2, 4], [3, 3, 3], [1, 1, 2], [2, 1, 1]) ➞ 63

totalVolume([2, 2, 2], [2, 1, 1]) ➞ 10

totalVolume([1, 1, 1]) ➞ 1

Notes

• You will be given at least one box.
• Each box will always have three dimensions included.
