The surface area of a cube is 13.5 m2. What is the length (in m) of its diagonal?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 1.5√3
Let the measure of each side of the cube be A meter.
The surface area of the cube = 6a2
According to the question -
6a2 = 13.5
a = 1.5
Diagonal of cube = a√3
Length of diagonal of cube = a√3 = 1.5√3
