Answer:
Some of the other answers are good examples of solving a system of three equations in three unknowns, which is what this problem is asking. Though the simplest way to solve this problem is actually to notice that, if we sum the three equations, we get:
X + Y = 10
X + Z = 20
+ Y + Z = 24
----------------
2X + 2Y + 2Z = 54
Factoring out the 2, we have 2(X + Y + Z) = 54, and dividing both sides by 2 reveals that X + Y + Z = 27.

Answer:
17.5 cubic feet
1163.75 pounds
Step-by-step explanation:
Givens
L = 3.5 Given
W = 5/7 * 3.5 Divide by 7
W = 5 * 0.5 Combine
W = 2.5
H = 4/5 * w
H = 4/5 * 2.5
H = 4 * 0.5
H = 2
Volume
V = L * w * h
V = 3.5 * 2.5 * 2
V = 17.5
Weight
1 Cubic foot Milk = 66.5 pounds
17.5 cubic feet milk = x
1 / 17.5 = 66.5/ x
x = 17.5 * 66.5
x = 1164.75
Answer:volume is lengthxwidthxheight
