Question 26
Mensuration of SolidsThe length and breadth of a cuboid are 15 cm and 8 cm respectively. If the volume of the cuboid is 1,560 cm3, calculate the total surface area.
- A.976 cm2
- B.838 cm2
- C.792 cm2
- D.746 cm3
Show the answer and explanation
Answer: B (838 cm2)
Explanation
Height = 1560 ÷ (15 × 8) = 13 cm. Total surface area = 2(15×8 + 15×13 + 8×13) = 2(120 + 195 + 104) = 838 cm².
