Hello, Lazarius
You see the fourmula to solve this is LxWxH so in this case we would multiply all thease numbers in order so 20 times 10 times 5 and get 1,000cm
Heres a better version
20cm*10cm*5cm= 1,000cm
I hope my answer helped you understand your question if did please leave a thank you rate my answer five stars and the most important mark me as brainliest thank you and have a great day!
