The first step is to find the area of the triangular base. The formula for the area of a triangle is bh/2, where b is the length of the base and h is the length of the height. Plugging in the dimensions you are given, you get 6*4/2=12 square centimeters. Multiplying this by the height of the prism, or 16, you get 12*16=192. Hope this helps!
