Answer:

184m^2

Step-by-step explanation:

Ok first we will look at the triangles.

The formula for triangles is 1/2bh

The base in our triangle is 6, and the height is 4. Also, we have 2 such triangles.

so, we need to plug in our values into our formula, and multiply it by 2, since there are 2 triangles.

2( 1 / 2 ( 6 ) ( 4 ) )

2 ( 12 )

24.

The area of the 2 triangles is 24.

Now, the next part is gonna be hard to explain, but I promise the final answer is right.

lets find the area of the rectangle in the middle. That's easy, 6*10 = 60.

Because the top rectangle would connect to the 5m side of the triangle, then the area of the rectangle would be 10*5 = 50

The same thing applies to the bottom rectangle, so its also 50.

24+50+50+60 = 184

The unit is meters(m)

So, 184 m^2

The surface area of the prism based on the net provided will be 184 square meters.

<h3>What is the surface area of a triangular prism?</h3>

Let h be the height and b be the base of the triangle.

Let L₁, L₂, and L₃ be the length and W be the width of the rectangle.

Then the surface area of the triangular prism will be

Surface area = 2 Area of triangle + 3 Area of rectangle

Surface area = h x b + (L₁ + L₂ + L₃) x W

From the figure, the length of the rectangles will be 5 m, 6 m, and 5m,  and the width is 10 m.

From the figure, the height is 4 m and the base is 6 m of the triangle. Then we have

Surface area = 4 x 6 + (6 + 5 + 5) x 10

Surface area = 24 + 16 x 10

Surface area = 24 + 160

Surface area = 184 square m

The surface area of the prism based on the net provided will be 184 square meters.

More about the surface area of a triangular prism link is given below.

Natali [406]

Answers:

  • Total equation:  x+y = 80
  • Legs equation:  2x+4y = 248
  • How many ducks? 36
  • How many cows? 44

====================================================

Further explanation:

  • x = number of ducks
  • y = number of cows

x+y = 80 is the total equation (ie the head count equation) since we assume each animal has 1 head, and there are 80 heads total.

That equation can be solved to y = 80-x after subtracting x from both sides.

The legs equation is 2x+4y = 248 because...

  • 2x = number of legs from all the ducks only
  • 4y = number of legs from all the cows only
  • 2x+4y = total number of legs from both types of animals combined

We're told there are 248 legs overall, so that's how we ended up with 2x+4y = 248

------------

Let's plug y = 80-x into the second equation and solve for x.

2x+4y = 248

2x+4( y ) = 248

2x+4( 80-x ) = 248

2x+320-4x = 248

-2x+320 = 248

-2x = 248-320

-2x = -72

x = -72/(-2)

x = 36

There are 36 ducks

Now use this x value to find y

y = 80-x

y = 80-36

y = 44

There are 44 cows.

------------

Check:

36 ducks + 44 cows = 80 animals total

36*2 + 44*4 = 72 + 176 = 248 legs total

The answers are confirmed.
