Find surface area and no the answer is not 60​

Mathematics

Illusion [34]2 years ago

The formula for calculating the surface area of a cuboid is

A = 2lw + 2hw + 2lh

where l = length, w = width, h = height

Let's calculate

A = (2 \times 6 \times 2) + (2 \times 5 \times 2) + (2 \times 6 \times 5)\\A = 104m^{2}

Answer:

104 m

Step-by-step explanation:

[] Surface area is the area of the surface. In other words, we will need to find the area of 6 rectangles and then add them together.

-> Since it is a rectangular prism, it will have three pairs of sides that are congruent. We can find the area of one of the sides and multiply it by two for all 6 as shown below. Then we just need to simplify.

2 (2 * 5) + 2 (6 * 5) + 2 (6 * 2)

2 (10) + 2 (30) + 2 (12)

20 + 60 + 24

80 + 24

104

104 m

[] Why is it not 60?

-> 60 is the area of the figure, not the surface area

Have a nice day!

     I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)

I need the steps and solution <br>-10x + 5y = 10 <br>x - 5y = -28​
natta225 [31]

−10x+5y=10

x−5y=−28

Rewrite equations:

x−5y=−28

−10x+5y=10

Step: Solve:

x−5y=−28

x−5y+5y=−28+5y(Add 5y to both sides)

x=5y−28

Step: Substitute:

−10x+5y=10

−10(5y−28)+5y=10

−45y+280=10(Simplify both sides of the equation)

−45y+280+−280=10+−280(Add -280 to both sides)

−45y=−270

−45y

−45

=

−270

−45

(Divide both sides by -45)

y=6

Step: Substitute:

x=5y−28

x=(5)(6)−28

x=2(Simplify both sides of the equation)

Answer:

x=2 and y=6

Midpoint of (16,5) and (-6,-9)?
Zigmanuir [339]

To solve this problem, we need to use the midpoint formula, where M = (x1+x2/2, y1+y2/2). To solve, we must plug in the given (x,y) values from our ordered pairs and then simplify, shown below:

(x1+x2/2, y1+y2/2)

( (16 + -6)/2, (5 + -9)/2 )

Now, we can begin to simplify by computing the addition in the numerators of both fractions.

(10/2, -4/2)

Next, we can finish the simplification process by dividing these fractions.

(5, -2)

Therefore, the midpoint of (16,5) and (-6,-9) is (5,-2).

Hope this helps!
