OpenStudy (tkhunny):

I believe the top is a triangle with edges 2.2 m 2.5 m and 3.3 m. It is then a sold created with height 0.54 m.

OpenStudy (rsadhvika):

it is a prism with triangular base

OpenStudy (anonymous):

yes

OpenStudy (rsadhvika):

you can use the prism formula then

OpenStudy (rsadhvika):

surface area = (perimeter of base)*h + 2*(area of base)

OpenStudy (anonymous):

Thank You

OpenStudy (rsadhvika):

you solved it ? :)

OpenStudy (anonymous):

well it doesnt come to the number i need

OpenStudy (rsadhvika):

what did u get

OpenStudy (anonymous):

i got 110.825

OpenStudy (rsadhvika):

surface area = (perimeter of base)*h + 2*(area of base) = (2.2 + 2.5 + 3.3) * 0.54 + 2*(1/2 * 2.2 * 2.5) = (8)*0.54 + 5.5 = 9.82

OpenStudy (anonymous):

ok i got it now Thank You
