In the "front"  we  have  a  6 - 8  - 10   right triangle

 

The area of  this  triangle  =  (1/2)(6 * 8)  =   24

 

The base is a   10 -  24  - 26    right triangle

 

The  area  of  this triangle  = (1/2) ( 10 * 24)  =  120

 

Another  triangle is one with a base  of 24  and a  slant height of  6.....its area   (1/2) (24 * 6)  = 72

 

And  the triangle  at the "back"  has a base of 26  and a height of  8

Its area =  (1/2)(26)(8)  =  104

 

So......the total surface area =  (24 + 120  +  72  + 104)   =  320 in^2

 

 

The volume=   (1/3)  area of base * height =   (1/3) (120)( 8) =  320 in^3
