Answer:
28 units³
Step-by-step explanation:
The volume (V) of the prism is calculated as
V = Al ( A is the area of end face and l is the length )
Here A =
and l =
, thus
V =
×
( cancel 21 and 3 by 3 and 2 and 8 by 2 )
=
×
= 7 × 4 = 28 units³
Answer: Sin N = 
Step-by-step explanation:
Since we have given that
In triangle MPN, ∠P=90°

As we know the formula for "Trigonometric Ratios":

By Pythagorus theorem , we get

So, we get,

Hence, Sin N = 
The lowest common denominator is 21
