Question

A 5cm^3 holds 936 grains of rice. How many grains of rice would fit in one Dutchtown elementary school classroom with the dimensions 16cm x 12cm x 22 cm?

Answer 1

Explanation:

The question wants us to find the quantity of rice grain the classroom will hold when the dimension of the classroom is 16cm x 12cm x 22 cm

To resolve the question, we will first have to find the capacity of the new volume

`\text{volume}=\text{length}* breadth* height=16*12*22=4224cm^3`

So, we can now rephrase the question as:

If a 5 cm cube holds 936 grains of rice, how many grains of rice will a 4224 cm cube hold

To do so, we have

Making x, the subject by cross multiplying as shown above

We will have the answer to be:

`790732.8\text{ grains of rice}`
