Formula for pyramid's volume: V = 1/3 l² h
Knowing that V = 560, l = 10 and h = 14, we can write it down as:
560 = 1/3 10 w 14
560 = 3 1/3w 14
560 = 10/3w 14
560 = 140/3w / 3 (both sides)
1680 = 140w / ÷ 140 (both sides)
w = 12
Doublecheck:
560 = 1/3 10 12 14
560 = 1/3 120 14
560 = 1/3 1680
560 = 560
So it's correct :)
