The length and breadth of a cuboid are 15cm and 8cm respectively. If the volume of the cuboid is 1,560cm³, calculate the total surface area.
- A. A. 976cm²
- B. B. 838cm²Correct
- C. C. 792cm²
- D. D. 746cm²
Explanation
Volume=l×b×h → h=1560/(15×8)=1560/120=13cm. Total surface area=2(lb+bh+hl)=2(15×8+8×13+13×15)=2(120+104+195)=2(419)=838cm².
