Let us calculate the total load over the RCC slab as shown below.

Given data:
Length of slab = 4500mm.=4.5m.
Width of slab = 3000mm. = 3.0m.
Slab thickness = 125mm. = 0.125m.
Calculation:
Total load over the slab
= [dead load + live load]
Where,
1. Dead load
= [self wt. of slab + floor finish]
a. Self wt. of slab
= [(volume of the slab) x density]
= [(length x breadth x thickness) x 25KN/m³]
= [( 4.5m. x 3.0m. x 0.125m.) x 25KN/m³]
= [1.6875m³ x 25KN/m³]
= 42.19KN.
b. Total load of floor finish
= [area of slab x wt. of floor finish /m².]
= [ (length x breadth) x 1.5KN/m²]
= [(4.5m. x 3.0m.) x 1.5KN/m²]
= [13.5m² x 1.5KN/m²]
= 20.25KN.
Total dead load
= [self wt. of slab + floor finish]
= [42.19KN + 20.25KN]
= 62.44KN.
2. Total live load over the slab
= [area of slab x live load /m².]
= [ (length x breadth) x 4KN/m²]
= [(4.5m. x 3.0m.) x 4KN/m²]
= [13.5m² x 4KN/m²]
= 54KN.
Total load over the slab
= [dead load + live load]
= [62.44 + 54]
= 116.44 KN
Total load over the slab in kg.
= [116.44 KN x 101.97]
= 11,873.39 kg.
Factored load of RCC slab
Wu = [1.5 x total load]
= [1.5 x 116.44]
Wu = 174.66 KN.
Factored load of RCC slab per unit area
W = [ total factored load ÷ area of slab]
= [ 174.66 ÷ (4.5 x 3)]
W = 12.94KN/m²
