Block wall painting

We color a wooden block with dimensions a = 4 cm, b = 3 cm, c = 2 cm and then cut it into cubes of 1 cm³. How many cats will she have?
a) just one wall painted
b) just two walls stained
c) just three walls painted
d) no painted wall?

Final Answer:

A =  4
B =  12
C =  8
D =  0

Step-by-step explanation:

$$\begin{gathered} a=4/1=4 \\ b=3/1=3 \\ c=2/1=2 \\ A=2+2=4 \end{gathered}$$

$B=6+6=12$

$C=8$

$$\begin{gathered} D=0 \\ \text{ Verifying Solution: } \\ {V}_1=A+B+C+D=4+12+8+0=24 \\ {V}_2=a\cdot b\cdot c=4\cdot 3\cdot 2=24 \\ {V}_1=V_2 \end{gathered}$$
