SSC CGL 2019 PYQ — Question 62

SSC CGL - 4th June 2019 - Shift 3 • Quantitative Aptitude • Q62

The areas of the three adjacent faces of a cuboid are 32 cm2, 24 cm2 and 48 cm2. What is the volume of the cuboid?

Show answer & explanation

Correct answer: D

Explanation

Correct answer is option 4 i.e. 192 cm3

Surface areas of 3 adjacent surfaces of a cuboid = lb, bh, hl

Volume = lbh

Hence,

Volume = √(Multiplication of SA of 3 adjacent surfaces) = √(lbh)

Given:

lb = 32, bh = 24, hl = 48 

Volume = √(lbh)

= √(32 × 24 × 48)

= √(16 × 2 × 2 × 4 × 3 × 3 × 16)

= 4 × 2 × 2 × 3 × 4

= 192 cm3
