Answer:
Diagonal of Cube = 25.98 cm
Step-by-step explanation:
Diagonal of cube² = edge² + edge² + edge²
Edge = 15cm
Diagonal of Cube² = 15² + 15² + 15²
=> Diagonal of Cube² = 15² × 3
=> Diagonal of Cube = √(15² × 3)
=> Diagonal of Cube = 15√3
√3 = 1.732
=> Diagonal of Cube = 15 × 1.732
=> Diagonal of Cube = 25.98 cm
