The length of BD is 14.3 cm to 1 d.p.
To find: Length of BD
In this cuboid, we need to find the length of BD, the hypotenuse of a right triangle with legs of length 6 cm and 5 cm.
BD² = BC² + DC²
BD² = 6² + 13²
BD² = 36 + 169
BD = √205
BD ≈ 14.3 cm
Therefore, the length of BD in the cuboid is 14.3 cm cm to 1 d.p.
