Polly used C) 45 cubic centimeters (45 = (2 x (3x2.5x1) + (10x3x1) )of clay if the thickness of the figure is 1cm. This problem can be solved by using a simple prism's volume equation which is volume = height x width x thickness. First, you must separate the model into three parts: two horizontal prisms (h: 3cm, w:2.5cm, t:1cm) and one vertical prism (h: 10cm, w:3cm, t: 1cm) in order to calculate the total volume of the model.
