Calculate 32713

Hello, I want to ask about the solution and procedure for my task, which is a cuboid with sides a=5cm, b=4 cm, and c=10 cm.
Calculate the area of the blue wall.
Calculate the area of the yellow wall.
Calculate the area of the green wall.
Calculate the surface area of ​​the cuboid.

Correct answer:

S1 =  20 cm2
S2 =  40 cm2
S3 =  50 cm2
S =  220 cm2

Step-by-step explanation:

a=5 cm b=4 cm c=10 cm  S1=a b=5 4=20 cm2
S2=b c=4 10=40 cm2
S3=a c=5 10=50 cm2
S=2 (S1+S2+S3)=2 (20+40+50)=220 cm2
