Question

The density of a certain material is such that it weighs 9 kilograms per cubic foot of volume. Express this density in grams per cup.

Answer 1

Given:

It is given that the density of a material can be expressed in such a way that it weighs 9 kg per cubic foot of volume.

To find:

We have to express the density of the given material in grams per cup.

Step-by-step explanation:

The density of the material is given to be  $9\textrm{ Kg}/\textrm{Cubic feet}$.

Now,  $1\textrm { Kg}$ is equivalent to  $1000\textrm { gm}$

And,  $1\textrm { Cubic Feet}$ is equivalent to  $119.69\textrm { cup}$

So,  $9\textrm{ Kg}/\textrm{Cubic feet}$ ≡ $\frac{9\times 1000}{119.69}\textrm { gm/cup}$

After simplification it gives,  $9\textrm{ Kg}/\textrm{Cubic feet}$ is equivalent to $75.2\textrm { gm/cup}$(Approximate)

Therefore, the density of the material is $75.2\textrm { gm/cup}$
