Unformatted text preview: as exact). The actual volume oF the dinosaur is V dino = 20 3 V m = 5 . 1021 m 3 . (c) Using ρ ≈ ρ w = 1000 kg / m 3 , we ±nd ρ = 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....
