Question

A 38.6 kg is a marble slab is shown above. what is the density

Answer 1

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

=
`$1564 \ cm^3$`

We know,

`$\text{density}= \frac{\text{mass}}{\text{volume}}$`

=
`$(38600)/(1564)$`

=
`$24.7 \ g/cm^3$`
