This week in Math 10 we started the Measurement Unit. This is one of my favourite units in math because we are dealing with real numbers. I have learned many new concepts this week during class. The one I am going to touch on in this blog post is: how to find the surface area and volume of right prism. A prism is a solid geometric figure whose two end faces are similar, equal, and parallel rectilinear figures, and whose sides are parallelograms. In other words, a prism is a geometric shape that has a identical top and base. To find the surface area of a prism you first need to look at the formula. SA=LxW. Surface area is always calculated in units squared. You can think of surface area like wrapping paper. To find the volume you can use one of the three formulas. V= BxhxH ,V= LxWxH or V= Base Area x H. When calculating volume you will use units cubed. Volume is the amount of space inside of a solid figure. So, let’s take a rectangular prism. Let’s have the W= 21.2cm , H = 5.1cm and the L = 20.4cm .
