Jamie just bought 2 boxes. The first box is square.With each side measuring 10units and is 4 units high.The second box is rectangular and has twice the volume of the square box. if the height of the second box is 5units and the width is 10 units what is the length of the second box.
for first box, l * l * h = 400
for second box, 800
l * b = 800 / 5 = 160
b = 10
l = 16
Thus, the answer is 16
