Answer:
It would take 64 1-cm cubes to construct a 4-cm cube.
Explanation:
The volume of a cube is equal to the edge raised to the power of 3.
A 1-cm edge cube has a volume of V₁ = (1 cm)³= 1 cm³
A 4-cm edge cube has a volume of V₄ = (4 cm)³= 64 cm³
The number of small cubes required to fill the same volume than the big cube is:

Answer:</h3>
D. CH₃O₆
<h3>
Explanation:</h3>
- We are given the ratio of carbon, hydrogen and oxygen in a compound as 14: 42 : 84
We are supposed to determine the empirical formula of the compound;
- We need to know what is an empirical formula;
- An empirical formula of a compound is a formula that shows the simplest whole number ratio of elements in a compound.
In this case;
The ratio of C : H : O is 14 : 42 : 84
- Note, this is not the simplest ratio.
But we can simplify further to get the simplest whole number ratio;
- Therefore, 14 : 42 : 84 is equal to 1 : 3 : 6
- Thus, the simplest whole number ratio of C : H : O in the compound is 1 : 3 : 6
- Therefore, the empirical formula of the compound is CH₃O₆
He is using the filtration method.
It’s a technique which is used for separation of solids and fluids by putting them through a medium which allows only fluid to pass through, leaving the solids (in this case the soil) alone.
The fluid that passed is called the filtrate.
