Step-by-step explanation:
Formula is 2(wl+hl+hw)
and dimensions are doubled so 5 is 10, 4 is 8, and 3 is 6.
2[(8x6)+(6x10)+(6x8)]
=376 cm^3
2 servings because one serving is 4%, so you would need would need to double that, or multiply it by two.
Answer:
Follow the followings steps to draw a quadrilateral with 4 unequal sides:
Step 1 : Draw line 
of length 10cm.
Step 2 : Construct 90° angle on with A as vertex and mark an arc of 5 cm on new arm of right angle. That's Point D.
Step 3 : Again Construct 90° angle on 
with D as vertex.
Step 4 : Mark an arc of length 6 cm on arm of 2nd right angle. Mark that point as C.
Step 5 : To complete the Quadrilateral, Join Point C and B.
A Quadrilateral (Specially mentioned Trapezoid) ABCD with four unequal side is constructed.
So, we have two equations. The first one is a/b = 2, and the other one is to find the value of 4b/a. In order to solve this, let's find the value of b/a. As you can observe, b/a is the reciprocal of a/b. Therefore, b/a is also the reciprocal of 2. This means that b/a = 1/2. Now, substituting this to the second equation, the answer would be
4b/a = 4(1/2) = 2
The answer is 2.
