Find diagonal

Find diagonal of cuboid with length=20m width=25m height=150m

Correct result:

d =  153.379 m

Solution:

l=20 m w=25 m h=150 m  d=l2+w2+h2=202+252+1502=5 941=153.379 ml=20 \ \text{m} \ \\ w=25 \ \text{m} \ \\ h=150 \ \text{m} \ \\ \ \\ d=\sqrt{ l^2+w^2+h^2 }=\sqrt{ 20^2+25^2+150^2 }=5 \ \sqrt{ 941 }=153.379 \ \text{m}
