Find the volume of the prism.
The basic formula for a prism is the area of the base times the height.
V = Bh
Since the base is a triangle, the first thing we gotta do is find the area of that triangle.
B = ½bhB = ½(10 in)(7 in)B = 35 in2
Now, we plug that value into the volume formula.
V = BhV = (35 in2)(8 in)V = 280 in3
