    Let's go slow and find the area of just the one face, the triangle with base 6 and height 8 the formula is 1/2 * base * height what do you get ?

    48 times 1/2 means 48/2 (it is not 96)

    yes. next the "back triangle" is the same area, it is also 24 so the front and back add up to 24+24= 48 now we have to find the area of the 3 rectangle shaped faces.
