The total surface area of a closed cube is 1350 cm2. What is the length of each side of this cube ?
Answer & explanation
Correct answer: option 3
We know that,
The total surface area of cube = 6 × (Side of the cube)2
We have,
The total surface area of cube = 1350 cm2
= 1350 = 6 × (Side)2
= Side 2 = 225
= Side = 15 cm
