i mean that prism

Ok, do you know the formula to find the area of a rectangle?
anonymous
  • anonymous
the formula my math gives me to find the answer is total area= ph+2B
anonymous
  • anonymous
Right! Remember that a capital P = permeter of the base, and capital B = area of the base. A = Ph + 2B So lets find the perimeter and area of the base.|dw:1363050666823:dw|
anonymous
  • anonymous
Can you tell me what is the perimeter of the base?
anonymous
  • anonymous
its not 6 is it?
anonymous
  • anonymous
No, that'd be the area though!
anonymous
  • anonymous
okay how do i find the perimeter then?
anonymous
  • anonymous
Remember, the perimeter is the sum of all the sides. For rectangles, there is a simple formula 2* length + 2*width
anonymous
  • anonymous
so its 10?
anonymous
  • anonymous
Right. (:
anonymous
  • anonymous
okayyy that helps a lot now i k how to do it
anonymous
  • anonymous
it ends up being 64 right?
anonymous
  • anonymous
if you could stay on this question please incase i have simular questions to ask
anonymous
  • anonymous
62 i meant
anonymous
  • anonymous
So we have: P = 6 B = 10 h = 5 A = Ph + 2B A = 6(5) + 2(10)

Sorry but I've gotta go. I'll be back in about 15-20 min.

Same steps. A = Ph + 2B So lets find the perimeter and area of the base. |dw:1363053998087:dw|
anonymous
  • anonymous
Perimeter = 12 * 4 = ? Area = 12 * 12 = ?
anonymous
  • anonymous
144

nvm ik how to do that one i need help with another

Find the lateral area for the prism.

  • anonymous
Great! Lateral area is the area of the faces, not including the bases of the figure. The formula for this is: LA = Ph (P = perimeter of the base) |dw:1363054464534:dw|We need to find the missing side length.
anonymous
  • anonymous
how do i do that? i forget is it 8?
anonymous
  • anonymous
To do this we use the Pythagorean theorem: \[\large a^2 + b^2 = c^2\]Where a, b, and c are the side lengths. ****c always stands for the hypotenuse(longest side)**** So we have: \[\large 6^2 + 4^2 = c^2\]\[\large 36 + 16 = c^2\]\[\large 52 = c^2\]Find the square root to solve for c.\[\large \sqrt{52} =\sqrt{c^2}\]\[\large 7.211 = c\]
anonymous
  • anonymous
And now we find the perimeter: |dw:1363054954194:dw|
anonymous
  • anonymous
so would the answer be 12+16(sqrt52)
anonymous
  • anonymous
?
anonymous
  • anonymous
Perimeter, you're simply adding all the sides. 6 + 7.2 + 4
anonymous
  • anonymous
no i meant the final answer
anonymous
  • anonymous
LA = (17.2)(8)

  • anonymous
ugh im confused very confused

http://hotmath.com/hotmath_help/topics/surface-area-of-a-prism.html does this show anything?
mathslover
  • mathslover
I think @jazy has done right
mathslover
  • mathslover
but to express in the terms I am also confused.
mathslover
  • mathslover
write it : \(\large{0 + 16\sqrt{13}}\) or \(\large{0 + 8\sqrt{52}}\)
