41.60 - 8.32 = 33.28
The <em>surface</em> area of the parallelpiped is equal to 800 square units.
<h3>What is the surface area of a parallelpiped?</h3>
The <em>surface</em> area of the parallelpiped seen in the picture is equal to the sum of the areas of its six faces, which are combination of areas of quadrilaterals and triangles. There are four parallelograms and two squares. Thus, the surface area of the solid is:
A = 2 · 8 · 20 + 2 · 7 · 20 + 2 · 10²
A = 800
The <em>surface</em> area of the parallelpiped is equal to 800 square units.

X, X+2, and X+4 are the three odd integers.
2(X)+(X+4)=25 represents the problem.
2X+X+4=25
3X+4=25
3X=25-4
3X=21
X=7
The answer for this is 37000
The cost of one chapstick is $1 and one eyeliner is $2.
Step-by-step explanation:
Let,
Cost of one chapstick = x
Cost of one eyeliner = y
According to given statement;
3x+2y=7 Eqn 1
4x+5y=14 Eqn 2
Multiplying Eqn 1 by 4
Multiplying Eqn 2 by 3
Subtracting Eqn 3 from Eqn 4
Dividing both sides by 7
Putting y=2 in Eqn 1
Dividing both sides by 3
The cost of one chapstick is $1 and one eyeliner is $2.
