If the lateral surface area of the cube is 144 cm2, then what is the length of its side?
Answer & explanation
Correct answer: option 4
We know that,
The lateral surface area of the cube = 4(side)2
According to the question, 4 × (side)2 = 144
side2 = \(\frac{144}{4}\) = 36
Side = \(\sqrt {36}\) = 6 cm
