SArea=2(LW + WH + LH)
SArea/2= LW + H(W+L)
H= (Sarea/2 -LW)/(W+L)

Given: L = 7cm, W = 5cm, As = 4.65m = 465cm,
As = 2W*h + 2L*h + 2W*L = 465,
10*h + 14*h + 10*7 = 465,
24h + 70 = 465,
h = 16.5 cm.
NOTE: 4.65 cm-surface is much to small for the given values L and W.
So I used 4.65 m. = 465 cm.
As = 2W*h + 2L*h + 2W*L = 465,
10*h + 14*h + 10*7 = 465,
24h + 70 = 465,
h = 16.5 cm.
NOTE: 4.65 cm-surface is much to small for the given values L and W.
So I used 4.65 m. = 465 cm.
