HELP QUICK! WILL GIVE BRAINLIEST!!!

The figure below shows a rectangular prism and a cube:

A rectangular prism and a cube are drawn side by side. The length of the rectangle prism is 5 inches, the width is 4 over 5 inch, and its height is 1 and 3 over 5 inches. The cube has a side length of 1 over 5 inch.

How many such cubes are required to completely pack the prism without any gap or overlap?


A) 1,029 R12
B) 1,706 R11

Find the volume of each and divide:

Volume of rectangle: 5 x 4/5 x 1 3/5 = 6 2/5

Volume of cube: 1/5^3 = 1/125

6 2/5 / 1/125 = 800

Answer:

800

Step-by-step explanation:

Let's calculate how many times the edge of the cube fits on the edge of the prism:

[tex]1\dfrac{3}{5}:\dfrac{1}{5}=\dfrac{(1)(5)+3}{5\!\!\!\!\diagup}\cdot\dfrac{5\!\!\!\!\diagup}{1}=5+3=8\\\\\dfrac{4}{5}:\dfrac{1}{5}=\dfrac{4}{5\!\!\!\!\diagup}\cdot\dfrac{5\!\!\!\!\diagup}{1}=4\\\\5:\dfrac{1}{5}=5\cdot\dfrac{5}{1}=5\cdot5=25[/tex]

Therefore we have new unit and new dimensions of the prism:

[tex]25\times4\times8[/tex]

Calculate the volume of a prism using the formula:

[tex]V=l\times w\times h[/tex]

Substitute:

[tex]l=25,\ w=4,\ h=8[/tex]

[tex]V=(25)(4)(8)=800[/tex]
