Question

Find the surface area of the triangular prism.

Picture below VV

Answer 1

use the forumla V= 1/4h √-a^4 + 2(ab)^2 + 2(ac)^2- b^4 + 2(bc)^2 - c^4

in your case:
a= 8
b= 15
c= 17
h= 13

this should come out to be 780

Answer 2

thanks

Answer 3

your welcome

Answer 4

surface area = 8 *15+17 *13+15* 13+8 *13=640 square units
