Calculate currency conversions for EUR, USD to RWF, and find the missing number in a sequence.

$$
1 \text{ USD} = \frac{993300 \text{ RWF}}{700 \text{ USD}} = 1419 \text{ RWF/USD}
$$

$$
110 \text{ USD} = 110 \times 1419 \text{ RWF}
$$
$$
110 \text{ USD} = 156090 \text{ RWF}
$$
So, $\boxed{110 \text{ USD} = 156090 \text{ RWF}}$.

Since the base is a square with side $20 \text{ cm}$:
$$
\text{Base Area} = \text{side} \times \text{side} = 20 \text{ cm} \times 20 \text{ cm} = 400 \text{ cm}^2
$$

The volume of a cuboid is given by $V = \text{Base Area} \times \text{Height}$.
$$
720000 \text{ cm}^3 = 400 \text{ cm}^2 \times \text{Height}
$$

$$
\text{Height} = \frac{720000 \text{ cm}^3}{400 \text{ cm}^2}
$$
$$
\text{Height} = 1800 \text{ cm}
$$
The height of the cuboid is $\boxed{1800 \text{ cm}}$.

Since the base is a square with side $20 \text{ cm}$:
$$
\text{Base Area} = \text{side} \times \text{side} = 20 \text{ cm} \times 20 \text{ cm}
$$
$$
\text{Base Area} = 400 \text{ cm}^2
$$
The base area of the cuboid is $\boxed{400 \text{ cm}^2}$.

$$
\text{Height} = \frac{375 \text{ cm}^3}{75 \text{ cm}^2}
$$
$$
\text{Height} = 5 \text{ cm}
$$
The height is $\boxed{5 \text{ cm}}$.

$$
\text{Height} = \frac{850 \text{ cm}^3}{50 \text{ cm}^2}
$$
$$
\text{Height} = 17 \text{ cm}
$$
The height is $\boxed{17 \text{ cm}}$.
