Question

the length of a diagonal of a cuboid having dimension 8cm,5cm and root 11 cm is d cm. write the value of d.​

Answer 1

Answer:

√((8)^2 + (5)^2) " = √89

d = √(√89^2 + √11^2) =√(89+11) = √100 = 10 cm Ans = 10 cm

Answer 2

length=8cm

bredth=5cm

height=√11cm

d=√l²+b²+h²=√8²+5²+√11²=√64+25+11=√100

√100=10

hence,d=10cm
