plz slove it with explanation

don't give unnecessary answer​

Answer 1

Given:-

• Length of cuboid = 30cm
• Breadth of cuboid = 25cm
• Height of cuboid = 20cm

To find:-

• Length of diagonal

Solution:-

Length of body diagonal of cuboid, D = $\sf \sqrt{l^2 + b^2 + h^2}$

D = $\sf \sqrt{30^2 + 20^2 + 25^2}$

D = $\sf \sqrt{900 + 400 + 625}$

D = $\sf \sqrt{1925}$

D = $\sf \bf{\sqrt{43.87}\;cm}$
