Randall built a scale model of a barn he wants to construct. What is the total volume of the model Round your answer to the nearest tenth. 3,254.0 cm^3
326.4 cm^3
3,100.8 cm^3
4,243.2 cm^3
1,305.6 cm^3

V = 3,264.0 cm^3

Step-by-step explanation:

They litterally didn't teach us THiS in this lesson, (I guessed the correct answer ) so what they said is ...

lwh + (1/2 bh) h

(20.4) (10) (11.2) + 1/2 (12) (8) (20.4)

= 2,284.8 + 979.2

= 3, 264.0

... I still couldn't understand it eye-

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg
