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 = ½bh B = ½(10 in)(7 in) B = 35 in^{2} Now, we plug that value into the volume formula. V = Bh V = (35 in^{2})(8 in) V = 280 in^{3} |
