Answer:

192 unit cubes.

Step-by-step explanation:

Let n represent number of cubes with each side 1/4 unit.

We have been given that a rectangular prism with a volume of 3 cubic units is filled with cubes with side lengths of 1/4 unit. We are asked to find the number of cubes that will fill that prism.

First of all, we will find volume of each cube.

\text{Volume of cube}=\text{Side length}^3

\text{Volume of cube}=(\frac{1}{4}\text{ unit})^3

\text{Volume of cube}=\frac{1^3}{4^3}\text{ unit}^3

\text{Volume of cube}=\frac{1}{64}\text{ unit}^3

The volume of rectangular prism will be equal to volume of n cubes.

\text{Volume of n cubes}=\text{Volume of rectangular prism}

n\times \frac{1}{64}\text{ Unit}^3=3\text{ Unit}^3

n\times \frac{1}{64}=3

n\times \frac{1}{64}\times 64=3\times 64

n=192

Therefore, it will take 192 unit cubes to fill the prism.

In the figure to the right, ABCD is a rectangle. Find the area of △ABC, if the area of △AOD is 10.
ehidna [41]
Assuming BOD and AOC are straight lines.

Area of the rectangle = 4 x ΔAOD
Area of the rectangle = 4 x 10
Area of the rectangle = 40 unit²

Area of ΔABC = 1/2 x 40 
Area of ΔABC = 20 unit²
