Hi, I'm Jimmy Chang, and we're here to talk about a math equation for prism laterals. Now the most popular equation involving prisms is that of the lateral area so we're going to talk about that as the main focus. Now the formula for that is LA is equal to P times H. Now what does LA mean? Well LA refers to the lateral area of the prism okay and then P stands for the perimeter of the prism and H is the height of the prism. Now just so you know, lateral area is a type of area so you're measuring two dimensions at once. Now with P being the perimeter it's just one kind of dimension and then H is the height which is yet a second dimension so when it comes to the lateral area of a prism, it's a pretty straightforward formula you just take the perimeter of it and then multiply by the height. So just plug it in and you should be good to go. So I'm Jimmy Chang and that's a math equation for prisms.
