Question

find the length of the diagonal of a cuboid with length=10 cm ,breadth=8 cm and height =4 cm

Answer 1

Length of diagonal = √ l^2 × b^2 × h^2

=(√10^2 + 8^2 +4^2 )cm

=(√100+64+16)cm

=(√180)cm

=13.41cm

Answer 2

Answer:

13.41640786

Step-by-step explanation:

diagonal (D) = under square root a*a+b*b+c*c

= under square root 10*10+8*8+4*4

= under square root 10*10+8*8+4*4

= under square root 180

= 13.41640786 square cm
