Question

A cube has and edge measuring 9cm. Find the number of edge 3 cm that can be cut.​

Answer 1

Step-by-step explanation:

ANSWER:-

GIVEN:-

• A cube whose measuring side is 9 cm
• We need to find the number of cubes that would be cut through it, 3 cm edge each

Concept:-

Surface Area and Volumes, 3D figures

Let's Go!

So, what we need to do is compare with the volumes.

We know that:-

Volume of cube = (side)³

So, we're gonna do that. First, with original and second with the desired unit.

Volume(Original) = 9³

= 729 cm³ is the volume.

Now, we need to find the number of cubes. Let the number of cubes be n. So,

$\sf{n \times 3^3 = 729}$

$\sf{n \times 27 = 729}$

$\sf{n = \dfrac{729}{27}}$

$\sf{n = 27 \ cubes}$

So, the required answer is 27 cubes.

Answer 2

Hello friend!

Here's ur answer! Volume of large cube = 9^3

= 729

Volume of small cubes =3^3

= 27

Let the no. Of cubes be x.

X* 27 = 729 =

X = 729/27

= 27

No. Of cubes =27
