Starter • Find the circumference and area for the circles with the given information • r = 10m • d = 6in • r = 4ft
Rectangular Prism Definition: a three-dimensional figure that has rectangles for all its faces Ex: cube, box
Volume of rectangular prism • The formula of a rectangular prism is: V = bwh (base x width x height)
Practice • Find the volumes of the following rectangular prisms: • B = 2in, w = 3in, h = 4in • B = 5cm, w = 1.5cm, h = 7cm • B = 12ft, w = 4ft, h = 5ft
Triangular Prism • A three-dimensional figure with bases that are triangles and side faces that are rectangles. • V = Bh where B = the area of the base • What is the base in this figure? • What formula will we use for B?
Practice • Find the area of each triangular prism by first finding the area of the triangle and then multiplying it by the height of the prism:
