Ok, do you know the formula to find the area of a rectangle?
 one year ago

mvrc1996Best ResponseYou've already chosen the best response.0
the formula my math gives me to find the answer is total area= ph+2B
 one year ago

jazyBest ResponseYou've already chosen the best response.1
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?
 one year ago

jazyBest ResponseYou've already chosen the best response.1
No, that'd be the area though!

okay how do i find the perimeter then?
 one year ago

jazyBest ResponseYou've already chosen the best response.1
Remember, the perimeter is the sum of all the sides. For rectangles, there is a simple formula 2* length + 2*width

okayyy that helps a lot now i k how to do it
 one year ago

mvrc1996Best ResponseYou've already chosen the best response.0
it ends up being 64 right?

if you could stay on this question please incase i have simular questions to ask
 one year ago

jazyBest ResponseYou've already chosen the best response.1
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 1520 min.

Find the total area of the prism.
 one year ago

jazyBest ResponseYou've already chosen the best response.1
Same steps. A = Ph + 2B So lets find the perimeter and area of the base. dw:1363053998087:dw

Perimeter = 12 * 4 = ? Area = 12 * 12 = ?

Find the lateral area for the prism.
 one year ago

jazyBest ResponseYou've already chosen the best response.1
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:dwWe need to find the missing side length.

how do i do that? i forget is it 8?
 one year ago

jazyBest ResponseYou've already chosen the best response.1
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.\[\large \sqrt{52} =\sqrt{c^2}\]\[\large 7.211 = c\]

jazyBest ResponseYou've already chosen the best response.1
And now we find the perimeter: dw:1363054954194:dw
 one year ago

mvrc1996Best ResponseYou've already chosen the best response.0
so would the answer be 12+16(sqrt52)

jazyBest ResponseYou've already chosen the best response.1
Perimeter, you're simply adding all the sides. 6 + 7.2 + 4

no i meant the final answer

I think @jazy has done right
 one year ago

mathsloverBest ResponseYou've already chosen the best response.1
but to express in the terms I am also confused.
 one year ago

mathsloverBest ResponseYou've already chosen the best response.1
write it : \(\large{0 + 16\sqrt{13}}\) or \(\large{0 + 8\sqrt{52}}\)
