A rectangular parallelepiped has dimensions 4 cm × 3 cm × 2 cm. Find its total surface area.
Show answer & explanation
Correct answer: B
Explanation
Total surface area of rectangular parallelepiped (Cuboid) = 2(lb + bh + hl)
Where, l = 4 cm, b = 3 cm, h = 2 cm
= 2[(4 × 3) + (3 × 2) + (2 × 4)]
= 2(12 + 6 + 8)
= 2 × 26
= 52 square cm
