<span>A cube is a geometric three-dimensional solid object. It constitutes
6 square faces, sides and three meeting at each vertex. It is the only regular
hexahedron. A cube has a fixed number of
perpendicular angles. Typically, it has 8 perpendicular angles and each spigolo
or corner has 3 angles. Since it has 8 perpendicular (⊥) angles and 3 angles in
each corner, it makes up 24 angles.
All 8 ⊥ angles and 3 angles in each corner mean: 8*3=24.
Therefore, a cube has 24 right angles.</span>

1644/4=411
Let x be the jug, 
for half-filled, y for the weight of the jug when empty.
∵ x + y = 2.6 kg
∵ x = 4 kg
∴ ⋅ 4 + y = 2.6 kg
∴ 2 + y =2.6 kg
∵ y = 2.6 - 2 = 0.6 kg
∴ The weight of the empty jug = 0.6 kg
Work shown above! Answer would be 2x^2 -16x + 30
