**Question 4.** **Asked on :**15 January 2019:09:24:30 AM

The total surface area of a cube is 150sq. cm. Find the perimeter of any one of its faces.

*-Added by Prince Rawat* **Mathematics** » **SURFACE AREAS AND VOLUMES**

**Answer:**

Total surface area of cube is 150sq. cm

Total surface area of cube : 6a^{2}

^{To find perimeter of its one faces : ?}

Total surface area of cube =150sq.cm^{}

6a^{2 }=150sq.cm

= 1506

= 25cm

=a^{2} = √25cm

=a = 5 cm

Perimeter of its one face is = 4 × a

= 4 × 5 cm

= 20 cm **Answer**
