Unit 11-10 prisms and surface area quick check questions multiple choice 1. identify the net of the trapezoidal prism. (1 point) a. an eight-sided shape is overlaid on a rectangle divided into two sections of different sizes, creating a combination of shapes comprising four rectangles stacked on top of each other and two trapezoids. the top-most rectangle has one vertical side labeled 9 cm. the next rectangle has one horizontal side of 12 cm and is bordered on two vertical sides by two trapezoids that appear to be the same size. one of the trapezoids is labeled 5 cm on its shortest parallel vertical side and 9 cm on one of its diagonal sides. the next rectangle has one vertical side labeled 9 cm. the bottom-most rectangle has one vertical side labeled 5 cm. b. an eight-sided shape is overlaid on a rectangle divided into two sections of different sizes, creating a combination of shapes comprising four rectangles and two trapezoids. two of the rectangles have one vertical side labeled 5 cm. one of the rectangles has one vertical side labeled 9 cm. the last rectangle has one horizontal side of 12 cm. this rectangle is bordered on two vertical sides by two trapezoids that appear to be the same size. one of the trapezoids is labeled 5 cm on its shortest parallel side and 5 cm on one of its diagonal sides. c. an eight-sided shape is overlaid on a rectangle divided into two sections of different sizes, creating a combination of shapes comprising four rectangles stacked on top of each other and two trapezoids. the top-most rectangle has one vertical side labeled 9 cm. the next rectangle has one horizontal side of 12 cm and is bordered on two vertical sides by two trapezoids that appear to be the same size. one of the trapezoids is labeled 5 cm on its shortest parallel vertical side and 9 cm on one of its diagonal sides. the next rectangle has one vertical side labeled 5 cm. the bottom-most rectangle has one vertical side labeled 9 cm. 2. what is the surface area of the rectangular prism?
