Answer:
168 in² area
120 in³ volume
Step-by-step explanation:
The surface area is the sum of the areas of the two congruent triangular bases and the three rectangular faces.
SA = 2(1/2)(6 in)(8 in) +(5 in)(6 in +8 in +10 in)
SA = 48 in² +120 in² = 168 in² . . . . surface area
__
The volume is half that of a cuboid with the same dimensions:
V = (1/2)LWH = (1/2)(8 in)(6 in)(5 in) = 120 in³ . . . . volume
