Can you guys please help me im confused
JulijaS [17]

Answer:

The bullet point between the numbers means times in this case, in some other cases it would mean "and" also known as plus. Therefore, the correct answer is the second one.

Step-by-step explanation:

In each half unit cube there is 6 cubes. ⇒

6 + 6 + 6 = 18 ⇒

But, this is not one of the options.⇒

So, we have to make the equation a bit different to solve it. ⇒

2 x 3 x 2, is the first option. ⇒

This is incorrect, as it equals 12. ⇒

The sum we are looking for is 18. ⇒

The second answer is 2 x 3 x 3. ⇒

This equals 18, we have found the correct answer. ⇒

So, there are a total of 3 half-unit cubes. ⇒

There are a total of 18 cubes. ⇒

I hope this helps!
