Answer:
for 2. I don't think it can be a triangle
General Idea:
We need to find the volume of the small cube given the side length of the small cube as 1/4 inch.
Also we need to find the volume of the right rectangular prism with the given dimension (the height is 4 1/2, the width is 5, and the length is 3 3/4).
To find the number of small cubes that are needed to completely fill the right rectangular prism, we need to divide volume of right rectangular prism by volume of each small cube.
Formula Used:

Applying the concept:
Volume of Small Cube:

Conclusion:
The number of small cubes with side length as 1/4 inches that are needed to completely fill the right rectangular prism whose height is 4 1/2 inches, width is 5 inches, and length is 3 3/4 inches is <em><u>5400 </u></em>
<span>The proper fraction is c. 3/4. A proper fraction is a fraction that is less than one. A fraction is less than one if its denominator, the number below the line, is larger than its numerator, the number above the line. 4/3 and 7/6 are both greater than one and 4/4 is equal to one, thus none of them are proper fractions.t</span>
Answer:
20.2 mm.
Step-by-step explanation:
2*2 + 2*8.1
= 4 + 16.2
= 20.2 mm.
Step-by-step explanation:
Angles in a quadrilateral add to 360 degrees. So, x = 360-88-142-106=24 degrees
