Answer:
The coefficient of y² will be 1, which we can see when we expand the expression:
(x + y)²
= (x +y)(x + y)
= x² + xy + xy + y²
= x² + 2xy + y²
252 cubic cm
Step-by-step explanation:
V = (l x w x h ) / 3
V = (6 cm x 9 cm x 14cm) / 3
V = 756/3 = 252 cubic cm

0.033 ft
Let g = 32.2 ft/s2 and h be the maximum height that water can be filled before the sides shatter.
Pressure is distributed from 0 to maximum at the bottom like the following equation:
So the force generated by water pressure on the side of the tank is
where s = 6ft is the side length of the tank. This force cannot be larger than 200lb
