Unformatted text preview: as exact). The actual volume oF the dinosaur is V dino = 20 3 V m = 5 . 1021 m 3 . (c) Using w = 1000 kg / m 3 , we nd = m dino V dino = m dino = ( 1000 kg / m 3 ) ( 5 . 1021 m 3 ) which yields 5 . 1 10 3 kg For the T. Rex mass. (d) We estimate the mass range For college students as 50 m 115 kg. Dividing these values into the previous result leads to ratios r in the range oF roughly 100 r 45....
