Question

A 38.6 kg marble slab is shown above. What is its density? Give your answer to the nearest tenth.

Answer 1

Answer: 24.7

Explanation:

Answer 2

Answer:

Density, $d=26.7\ g/cm^3$

Explanation:

The attached figure shows a 38.6 kg marble slab. The dimensions of the marble slab is 23 cm × 17 cm × 4 cm

Density = mass/volume

Volume of a cuboid shape is equal to, V = 23 cm × 17 cm × 4 cm

V = 1564 cm³

Density,

$d=\dfrac{38.6\times 10^3\ g}{1564\ cm^3}\\\\d=24.68\ g/cm^3$

or

$d=26.7\ g/cm^3$

So, the density of the marble slab is $26.7\ g/cm^3$.
