**Solution —**

Here, l= 15 m, b = 12 m and h = 4.5 m.

Volume of the cuboid = (l×b×h) cubic units

= (15 ×12 ×4.5) m³

** = 810 m³.**

Total surface area of the cuboid

= 2(lb+ bh+ lh) sq unit

= 2(15 ×12 +12× 4.5 +15 ×4.5) m²

**= 603 m²**

Lateral surface area of the cuboid

= [2(l+b) × h] sq unit

= [2(15 +12)×4.5] m²

**= 243 m²**
