A rectangular box has a base and four vertical sides but no top. L = length, W = width, H = height of the box. The sum of the length, width and height is 7. Express the total area of the base and four sides of the box in terms of L and W Answer is a(L+W)+bLW +c(L2 +W2)
with a =? b = ? c = ?
What should L, W, H be to give the largest total area ? L= ? W=? H=?

M∠Z > m∠X + m∠Y
m∠X + m∠Y + m∠Z = 180°
m∠X + m∠Y = 180°- m∠Z
m∠Z > 180° - m∠Z
2 m∠Z > 180°    /:2
m∠Z > 90°  ( A, B and C are not possible )

D ) m∠X + m∠Y < 90°
