We can make 5 such rectangles
use your intuition and draw a diagram that shows all the different possiblities
Answer:
y= 
Step-by-step explanation:
To find inverse of something, just switch the variables
x=y^2
now try to solve back in terms of y
y= 
Sec is the length of the hypotenuse divided by the length of the adjacent side.
Meaning divide 20/16
Meaning your secant or sec is 1.25 or 1 1/4
Volume of one cubic block = (1/6)^3 = 1/216 cu ins
Volume of the prism = 1/3 * 2/3 * 2/3 = 4/27 cu ins
Number of blocks to fill prism = 4/27 / 1/216 = (216*4) / 27 = 32
The best thing is to have a ruler with the appropriate units to construct these triangles;)
