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**
