First we neeed to find the volume of the rectangular prism




Volume of cube with side lengths 1/6 = 1/6 x 1/6 x 1/6 = 1/216
The number of cubes needed to fill the prism without gaps or overlaps =



Okay first, use the sin rule (

so

sin^-1 this and you get 47.928....this is angle ADB
and as it is on a straight line, 180 - this angle gets ADC
180 - 47.928.... = 132.07
I'm 100% sure the answer is d. II and IV
because $257.72 - $248.53 = $9.19
and $73.98 - $64.79 - 9.19
i hope this helps :)
Y = 180 - 51 -56 = 73
x = 180 - 73 - 72 = 35
x = 35 degrees
A. Yes, since a square is a type of rectangle, but it has four congruent and parallel side.
B. Yes, since a square is also a type of parallelogram. Therefore it has 2 pairs of parallel sides.
C. No, they have 2 pairs of congruent sides.
Hope this helps :D
