<font size="4">


"The volume of a rectangular storage box is 1440in cubed"
V = 1440


Length: L = 20

"it is half as tall as it is wide"
Width = W
Height: H = W/2


Volume of the box
V = L*W*H
V = 20*W*(W/2)
1440 = 20*W*(W/2)
1440 = 10*W^2
10*W^2 = 1440
W^2 = 1440/10
W^2 = 144
W = sqrt(144)
W = 12


H = W/2
H = 12/2
H = 6


Width = <font color="red">12 inches</font>
Height = <font color="red">6 inches</font>
