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

Same steps. A = Ph + 2B So lets find the perimeter and area of the base. |dw:1363053998087:dw|
Perimeter = 12 * 4 = ? Area = 12 * 12 = ?
144
nvm ik how to do that one i need help with another
Find the lateral area for the prism.
1 Attachment
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.
how do i do that? i forget is it 8?
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.\[\large \sqrt{52} =\sqrt{c^2}\]\[\large 7.211 = c\]
And now we find the perimeter: |dw:1363054954194:dw|
so would the answer be 12+16(sqrt52)
?
Perimeter, you're simply adding all the sides. 6 + 7.2 + 4
no i meant the final answer
LA = (17.2)(8)
ugh im confused very confused
this is what its asking me to fill in

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