Best ResponseYou've already chosen the best response.1Ok, do you know the formula to find the area of a rectangle?

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

Best ResponseYou've already chosen the best response.1Right! 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

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

Best ResponseYou've already chosen the best response.0okay how do i find the perimeter then?

jazy

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

Best ResponseYou've already chosen the best response.1So we have: P = 6 B = 10 h = 5 A = Ph + 2B A = 6(5) + 2(10)

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

Best ResponseYou've already chosen the best response.1Perimeter = 12 * 4 = ? Area = 12 * 12 = ?

Best ResponseYou've already chosen the best response.0Find the lateral area for the prism.

jazy

Best ResponseYou've already chosen the best response.1Great! 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.

Best ResponseYou've already chosen the best response.0how do i do that? i forget is it 8?

jazy

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

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

jazy

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

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