What is the greatest number of cubes with a side of 1.5cm that can fit in the box with dimensions 16cm ×5cm ×12cm? Please help me ASAP.

Respuesta :

Answer: 284 cubes.

Step-by-step explanation:

By definition, the volume of a rectangular prism can be calculated by multiplying its dimensions.

Knowing that the dimensions of this box are [tex]16cm*5cm*12cm[/tex], we get that the volume of the box is:

[tex]V_{box}=16cm *5cm *12cm=960cm^3[/tex]

The formula for calculate the volume of a cube is:

[tex]V=s^3[/tex]

Where "s" is the lenght of a side.

Kwnowing that the a cube has a side of 1.5 cm, we get that the volume of one cube is:

[tex]V_{cube}=(0.5cm)^3=3.375cm^3[/tex]

Dividing [tex]V_{box}[/tex] by [tex]V_{cube}[/tex] we get the greatest number of cubes  that can fit in the box:

[tex]number\ of\ cubes=\frac{960cm^3}{3.375cm^3}=284[/tex]

Answer:

240 cubes

Step-by-step explanation:

16/1.5 = 10.6...

5/1.5 = 3.3...

12/1.5 = 8

10*3*8=240
