Answer 1

If I’m correct, it’s 5 since x•x•5=24 isn’t doable

Answer 2

Answer:

5 is the answer.

Review:

What is a cuboid?

A cuboid is a rectangle, but in 3D form.

Do we calculate area or volume in a cuboid?

We calculate the volume for 3D shapes. For 2D shapes, area is used.

If/Then:

Now, if the volume of the cuboid is 24 units³ then:

x × x × y

Now, lets fit all our options to see which one is NOT the dimensions.

Option A:

x × x × 3 = 24 units³

x × x = 12 units³ ✔

This is possible.

Option B:

x × x × 4 = 24 units³

=> x × x = 6 units³ ✔

This is possible.

Option C:

x × x × 5 = 24 units³

=> x × x = 24/5 units³ ❌

This is not possible. This will be our answer.

Option D:

x × x × 6 = 24 units³

=> x × x = 4 units³✔

This is possible.

Conclusion:

So after working on our problem, we can conclude that C is our answer. Hoped this helped.
