Mathematics for IGCSE & O level - Pythagoras' Theorem And Trigonometry (Section 1 - No. 4)
What is the formula for calculating the length of the diagonal of a cuboid with sides a, b, and c?
d = a² + b² + c²
d = √(a² + b² + c²)
d = a + b + c
d = 2(ab + bc + ac)
설명
The length of the diagonal is found using the formula: d = √(a² + b² + c²)
