Which question do you want answered? All of them?
9) V = Bh, where B = area of base and h = height
V = (4.5 in)(3.5 in)(7 in)
V = 110.25 in³
10) V = Bh
V = (72 in)(24 in)(36 in)
V = 63945 in³
11) V = Bh; (Area of Rectangle A)x = Area of Rectangle B
Rectangle A:
V = (6 in)(4 in)(5 in)
V = 120 in³
Rectangle B: 
V = (6×2 in)(4×2 in)(5×2 in)
V = (12 in)(8 in)(10 in)
V = 720 in³
120x = 720
x = 8
12) V = Bh
V = (4 cm)(2 cm)(5 cm)
V = 58.4375 cm³
13) V = Bh; Volume of juice = .90 (90%) × Volume of box
V = (6 in)(2 in)(4 in)
V = 65 in³
Volume of juice = .90 × 65 in³
Volume of juice = 58.5 in³
14) Density = 
V = Bh
V = (16 cm)(2.5 cm)(5 cm)
V = 200 cm³
Density = 19.3 g/cm³
19.3 g/cm³ = 
mass = (19.3 g/cm³)(200 cm³)
mass = 3860 g
15) V = Bh
V = (1 ft)(1 ft)(1 ft)
V = 2.734375 ft³
Hoped that helped!
