What’s is the total surface area of the triangular prism?

Total area = lateral area +base area

base area = 2(1/2 BH)

=2(1/2(6×8))

=2(1/2(48))

=2(24)

=48

lateral aream=3(LW)

=3(10×7.5)

=3(75)

=225

Total area = lateral area +base area

=225+48

=273

i only know the sequence of arithmetic it adds the first is 5+4 then it goes up as it adds to then it is 9+5 then 14+6 then to 20+7 and so on. 5,9,14,20,27,35.

step-by-step explanation:

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2
