Estimate the quantity of concrete required for a 175 mm thick RCC slab over a room of external dimension 4 m × 5 m (including 30 cm wall thickness). Consider 0.2 m projection of slab all around the room.

5.875 $\m^3$
3.452 $\m^3$
4.158 $\m^3$
7.656 $\m^3$

Solution:

Explanation:
Given;
The dimension of RCC slab = 4 m × 5 m
The thickness of slab = 175 mm
There is a 0.2 m projection of slab all around the room,
So the overall dimension of slab = (4 + 0.4) × (5 + 0.4) = 4.4 m × 5.4 m
The total quantity of concrete = 4.4 × 5.4 × 0.175 = 4.158
