Can you guys please help me im confused

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!

How to solve this brainteaser
laila [671]

Answer:

last row equals 333

Step-by-step explanation:

The clock showing time 9:00 should be worth 9 points, and the clock showing 3:00 should be worth 3 points, giving for the first row:

9 + 9 + 3 = 21

the three equal calculators showing 1234 are worth 10 points each:

1+2+3+4 = 10

and 10 + 10 + 10 = 30

the light bulbs should be 15 points each then giving 15 + 15 - 15 = 130 - 15 = 15 Notice also that they all have 5 rays of light coming out (so a 3 points per ray)

Now for the bottom line we have:

9 + (1+2+2+4) times 3 * 12 (only four rays on each bulb thus 4 * 3 = 12)

Notice we added the figures that appear in the calculator.

9 + 9 * 36 = 333
