Change in Dimensions To calculate the original volume I did…____×____×____ With the volume doubled I did… _______×_______×_______ _______×_______×_______ = _______ The original volume was multiplied by a scale factor of 8! – (8)(12 cubic cm) = 96 cubic cm 4 3 1 4 3 1 (2) 8

Change in Dimensions Sandy doubled the width, tripled the length, and quadrupled the height of a rectangular prism. How would the original volume of the rectangular prism change? Explain why in complete sentences. 2(w) x 3(l) x 4(h) 2 x 3 x 4 = 24 The original volume will change by a scale factor of 24!
