What do we know about Mount Everest? Well, we know it's in Nepal. We know it's in the Himalayas. We know it's the highest mountain on earth (8,848 metres). We know that over 250 climbers have lost their lives attempting to reach the summit, and that a film called Everest has just been released.

We know that in 1953, Edmund Hillary and Tenzing Norgay became the first people to reach the summit. We know that Bear Grylls climbed it when he was just 23, and that over 4,000 climbers have reached the summit in total. In conclusion, we know a lot about it.

But do you, for example, know how many Big Macs you'd need to have a tower of Big Macs as high as the world's tallest mountain? Or, how many times you'd have to pile Everest on top of itself to reach the moon? Nope? Never fear, Mpora is here.

1) How Many Big Macs?!

If you stacked 126,671 and a half Big Macs on top of each other you'd have a tower of Big Macs as high as Mount Everest.

Mount Everest is 884800 centimetres high.

The average Big Mac is only 6.985 centimetres high.

884800cm/6.985cm = 126,671.4 Big Macs

If you stood on the summit of Mount Everest and shouted extremely loudly (you'd have to shout really, really, really loudly), it would take approximately 25.78 seconds for your voice to reach sea level.

Sound travels at one kilometre every 2.914seconds.

Mount Everest is 8.848km from top to bottom.
