The question is incomplete. The dimension of the marble slab is 23 cm by 17 cm by 4 cm.
Solution :
Given
The mass of the marble slab, m = 38.6 kg
= 38600 g
Length, l = 23 cm
breadth , w = 17 cm
Thickness, h = 4 cm
Therefore, volume of the slab is V = 23 x 17 x 4
=
![$1564 \ cm^3$](https://img.qammunity.org/2021/formulas/mathematics/college/casgy183f3yu9ajt8zvno89gn9nbyy4av5.png)
We know,
![$\text{density}= \frac{\text{mass}}{\text{volume}}$](https://img.qammunity.org/2021/formulas/mathematics/college/8l2wcsbodd40xd1dt4c57wdqwijhvk48jb.png)
=
![$(38600)/(1564)$](https://img.qammunity.org/2021/formulas/mathematics/college/j0hclzb7fet7hw50j3ukqbvfcz7qpcp17m.png)
