The cube-shaped cube box has dimensions of 30 cm × 30 cm × 12 cm. How many CZK (Czech crowns) would it cost to be the biggest cake that would fit into the box when a 10 cm³ cake costs CZK 0.5? The cake has the same shape as the box.

Correct answer:

x =  540 Kc

Step-by-step explanation:

$$\begin{gathered} V=30\cdot 30\cdot 12=10800{\text{cm}}^3 \\ {V}_2=10{\text{cm}}^3 \\ x=\frac{V}{V_2}\cdot 0.5=\frac{10800}{10}\cdot 0.5=540\text{Kc} \end{gathered}$$
