““So, let’s review how to figure volume. Volume is merely: area × depth = cubic feet. In other words, square feet (the area) times the depth equals cubic feet. Our 4 × 4-foot box is 16 square feet in area (that’s 4 feet times 4 feet). If it were 1 foot deep, the volume would be: 16 (the area) times 1 (the depth) equals 16 cubic feet. But it’s not 1 foot deep, it’s only 6 inches deep so we need only one-half or just 8 cubic feet for our 4 × 4 box. The math looks like this: 4 times 4 divided by one-half foot equals 8. Or to show it mathematically, (4 × 4)/2 = 8. (Now don’t laugh, kids, some of the parents will be thankful for this kind of help).””
