Answer:
960cm³
Step-by-step explanation:
Find the base of the triangle (use phytagoras theorem)
c²= a²+b²
20²= 16²+b²
400=256+b²
b²=400-256
b²= 144
b=
base= 12
Volume: (1/2×b×h)×l
= (1/2×12×16)×10
=(6×16)×10
=96×10
=960cm³
Solution :
It is given that :
lies in the first quadrant.
And lies in the fourth quadrant.
Since, and
(given)
Similarly
(IVth quadrant)
Therefore,
