Answer 1

What do you need help with :P You ca post your question as a thread instead of 'help', because we are all here to help =)

Answer 2

A chocolate bar measures 40 mm wide, 80 mm long, and 5 and 1 over 2 mm high. Will’s Wrapping Company is making a wrapper to cover the chocolate bar. Use the correct net and determine how much paper will be needed to make the wrapper.

The net of a rectangular prism with a height of 40 millimeters, a length of 80 millimeters, and a width of 5 and 1 over 2 millimeters.

Will’s Wrapping Company needs 3,860 mm2 of paper to wrap the chocolate bar.
Will’s Wrapping Company needs 7,720 mm2 of paper to wrap the chocolate bar.
Will’s Wrapping Company needs 8,160 mm2 of paper to wrap the chocolate bar.
Will’s Wrapping Company needs 15,440 mm2 of paper to wrap the chocolate bar.

Answer 3

:( All I see is black diamonds with question marks. Give me a sec to refresh

Answer 4

Well, that means we need to find the area of the rectangular prism. Do you know the formula to use when finding the area of this prism?

Answer 5

no

Answer 6

The formula is \(\rm \color{blueviolet}{A~=~2(wl~+~hl~+~hw)}\) Where w = width, h = height, and l = length.

We know that
w = \(\rm \color{blueviolet}{5\dfrac{1}{2}mm}\)

l = \(\rm \color{blueviolet}{80mm}\)

h = \(\rm \color{blueviolet}{40mm}\)

So we have to plug in the values in the formula

\(\rm \color{blueviolet}{A~=~2(5\dfrac{1}{2}\times 80~+~40\times 80~+~40\times 5\dfrac{1}{2})}\)

Can you solve that?

Answer 7

We can convert \(\rm \color{blueviolet}{5\dfrac{1}{2}}\) to \(\rm \color{blueviolet}{5.5}\) to make things easier

\(\rm \color{blueviolet}{A~=~2(5.5\times 80~+~40\times 80~+~40\times 5.5)}\)

@sjman1

Answer 9

THANKKK U SOO MUCH U DONT EVEN KNOW HOW BAD I needed your help :) @sammixboo

Answer 10

so the awnswer is A? @sammixboo

Answer 11

:P you forgot to multiply it by 2

Answer 12

And no problem =)

Answer 13

i think its c? @sammixboo

Answer 14

Hmm no :( But let's solve this problem together!

\(\rm \color{blueviolet}{A~=~2(5.5\times 80~+~40\times 80~+~40\times 5.5)}\)

We have to do what is int he parenthesis first, and in the parenthesis we have to do all the multiplication first starting from the left side of the equation

\(\rm A~=~2(\color{blueviolet}{5.5\times 80}~+~40\times 80~+~40\times 5.5)\)

What is 5.5*80?

Answer 15

440? @sammixboo

Answer 16

Correct, so we have


\(\rm \color{blueviolet}{A~=~2(440~+~40\times 80~+~40\times 5.5)}\)

Now onto the next multiplication =)

\(\rm A~=~2(440~+~\color{blueviolet}{40\times 80}~+~40\times 5.5)\)

What is 40*80?

Answer 17

3200? @sammixboo

Answer 18

3200? @sammixboo

Answer 19

Correct! Onto the next multiplication. What is Correct, so we have


\(\rm \color{blueviolet}{A~=~2(440~+~3200~+~40\times 5.5)}\)

Now onto the next multiplication =)

\(\rm A~=~2(440~+~3200~+~\color{blueviolet}{40\times 5.5})\)

What is 40*5.5?

Answer 20

220?

Answer 21

Good so we have

\(\rm \color{blueviolet}{A~=~2(440~+~3200~+~220)}\)

ow, still working in the parenthesis, what is 440 + 3200 + 220?

Answer 22

3860? @sammixboo

Answer 23

Correct, so now we have A = 2*3860

Answer 24

So what is 2*3860?

Answer 25

7720

Answer 26

@sammixboo 7720

Answer 27

Yes =) And that is your answer

Answer 28

thank u 4 being patient :)
