Question

The length, breadth and height of a cuboid are (log 125 + log 8), (log 1000 – log 10) and log 10
respectively. Find the total surace area of the cuboid.

​

Answer 1

Answer:

Volume of the cuboid = 22 square units

L = log 125 + log8 = log 5³ + log 2³

Using and

Thus,

L = 3 log 10

B = log 1000-log 10 = log 10³ - log 10 = 2 log 10

H = log 10

So,

Total surface area = 2 (lb + bh + hl) = 2 ( (3 log 10 × 2 log 10) + (2 log 10 × log 10) + (log 10 × 3 log 10) ) = 22 × (log 10)²

log 10 = 1

So,

Volume of the cuboid = 22 square units
