Answer:

8 : 1

Step-by-step explanation:

Given ratio of sides = a : b, then

ratio of area = a² : b²

ratio of volumes = a³ : b³

Given

ratio of areas = 384 : 96 = 4 : 1 ← in simplest form, then

ratio of sides = $\sqrt{4}$ : $\sqrt{1}$ = 2 : 1

Hence

ratio of volumes = 2³ : 1³ = 8 : 1

Answer:

Total volume of the figure = 1067 cm³

Step-by-step explanation:

Volume of the composite figure = Volume of the rectangular prism + Volume of the square pyramid

Volume of the rectangular prism = Length × Width × Height

= 10 × 10 × 7

= 700 cm³

Volume of the square pyramid = $\frac{1}{3}(\text{Area of the base})\times (\text{height})$

= $\frac{1}{3}(\text{Side})^2$ × height

= $\frac{1}{3}(10)^2(18-7)$

= 366.67 cm³

Total volume of the composite figure = 700 + 366.67 = 1066.67 cm³

≈ 1067 cm³
