Tarzan :

Not enough data to calculate the height, everybody assume ratio on the wall is 1:1, but there’s no info on the source and angle of light, and nothing in puzzle says this is sun light.

Medusathecatlady🎀🎀 :

silly math= green is 2 which is 3-1. so red is (6-1)+(4-1)= 5+3=8

Re_ez :

8cm. The 2cm bar becomes 3cm as a shadow, so its a 2:3 ratio. The shadow for the taller bar(excluding the wall shadow) is 6, so using a 2:3 ratio, 6cm as a shadow would be 4cm as the bar. Adding the extra 4cm on the wall, it’ll be 8cm tall

Benja :

I said 8 but I didn’t do all that weird math.

Ptparrish :

4cm high shadow on the wall is twice height of the green bar, meaning if the wall wasn’t there, the shadow of the red bar would extend 6cm further, which means the shadow of the red bar should be 12cm. If the shadow is 12cm (4x the length of the green bar’s shadow), then the height of the red bar is 4x the height of the green bar, or 8cm.

PaviosPeta :

The 6 meter shadow represents 2/3 of its corresponding tower portion but the 4 Meter shadow represents 100% of its corresponding tower portion. So 2/3 of 6 is 4. 4+4 is 8 done

Dopamine rich :

The shadow is 1/3 taller. Which means the red pillars shadow height should be 12m. Then you can basically solve the rest in your head

Hillman :

2m creates 3m on the ground means 6m on the ground was created by 4m then plus 4m shadow which was created by the rest of the barre gives 8m total

jambawamba23🇨🇦 :

Yup. Very easy math for any person on the street to do in their head.

kennyb0486 :

shadow is 4 half of the wall and the column is same height as wall. eye balled it

Ђорђе 007 :

2/3 of 10 =6,666666666666666666666666

Jo Shlepp :

ratio of green to its floor shadow is 2:3 Ratio of red to to its floor shadow should also be 2:3, floor shadow is 6 so red must be 4 up to the point where it casts a shadow on the floor. Then add 4 for the shadow on the wall you get 8

Latertater20231129 :

Pretty sure it’s 8 without doing any fancy formulas or verifying the wall specifics

Travelling 🌻 :

6.666m - I have no idea really, but wanted to join in

Lix_x :

Based on Green, tower is 2/3 of shadow. 2/3 of red shadow is 4. Shadow on upright wall has not distortion so is 4. 4+4 is 8

Mes :

It’s clearly 8. 2(2)+4=8, it’s that simple

Yo'Sai :

9m

Jokke_r :

you over complicated it, you know the shadow to height ratio is 2/3, we can look at the upper part of the red bar, it's shadow end at the wall at 6m, so what height of an object would produce a 6m shadow, answer is 4, as it's just 2/3 doubled, then we just add the already vertical part of the shadow, so 4+4=8

stealthsport1 :

6 ÷ 3 = 2 2 × 2 = 4m 4 + 4 = 8m Answer = 8m

St. Peter :

The ratio of bar to shadow is 2:3, assume the 4m shadow to be rigid, then that 4m bar will produce a 6m shadow. So 6m shadow plus another 6m shadow is 12m shadow if there was no purple wall. And using the ratio, a 12m shadow could only be from a 8m bar

Dane :

NEL :

does the position of the light affect the shadow?

Souricci :

6,33 cm

Mavo :

he is right it is 8 he used more complex math. I used this 3÷2= 1,5 6÷1,5= 4 4+4= 8 the answer is 8
