Question

Volume with cubes with fraction lenghts.32cm 2cm 1 cm

Answer 1

You will need 24 cubes to fill the prism.

Step by step explanation:

Volume cube:

`V=(3)/(2)\cdot1\cdot2\text{ = 3}`

Cube with side lengths of 1/2.

`V\text{ = }(1)/(2)\cdot(1)/(2)\cdot(1)/(2)\text{ = }(1)/(8)=0.125`

Then.

The simple rule of 3 is an operation that helps us to quickly solve problems of proportionality, both direct and inverse.

To make a simple rule of three we need 3 pieces of information: two magnitudes proportional to each other, and a third magnitude. From there, we will find out the fourth term of proportionality.

So first you multiply 3 by 1. and then divide the result by 0.125.

`3\cdot1\text{ = 3}`
`(3)/(0.125)\text{ = 24}`
