The areas of the three adjacent faces of a cuboid are 322, 242 and 482 . What is the volume of the
cuboid?
128 cm3
26 cm3
288 cm3
192 cm3
Let's break it down:
- Let cuboid sides be a, b, c.
- Areas of adjacent faces: ab = 32², bc = 24², ca = 48².
- Volume = abc.
- abc = v[(ab) × (bc) × (ca)]
= v[(32²) × (24²) × (48²)]
= v[(32 × 24 × 48)²]
= 32 × 24 × 48 = 36,864
- But need *cube root* if looking for abc:
Actually, v[(ab) × (bc) × (ca)] = abc
So:
abc = v[(32²) × (24²) × (48²)]
= v[1024 × 576 × 2304]
= v[1358954496]
= 36864
Wait, this is much more than any options given. Check calculation:
abc = sqrt[(ab) × (bc) × (ca)]
= sqrt[32² × 24² × 48²]
= sqrt[(32 × 24 × 48)²]
= 32 × 24 × 48 = 36864
There must be something missing. But volume in cm³ is 36864 cm³, but the face areas were 32, 24, 48 squared WITHOUT units stated. However, per options, change the calculation:
Perhaps, face areas ARE 32, 24, 48 (not 32², 24², 48²):
- ab = 32
- bc = 24
- ca = 48
abc = sqrt[32 × 24 × 48]
32 × 24 = 768
768 × 48 = 36864
sqrt[36864] = 192
So, the correct answer is: Option:4, Volume = 192 cm³
Explanation:
- For volume, multiply (ab × bc × ca) and take square root.
- Does this:
32 × 24 × 48 (face areas) = 36864
Square root = 192
So, Option 4 is correct.
- Other options (128, 26, 288) do not match this result.
Correct Answer: Option:4, 192 cm³
