Q= 14 and 1/3 (fourteen and one third)
Volume of prism B=800*6³/8³
=800*27/64
=25*27/2
=575/2
=287.5 cm³
If the two lengths are 7 and 3, then I believe the length of the hypotenuse would be approximately 7.62.
If I follow the angle degrees that they gave, your answers would be as follows:
I=145°
S=155° or 90°
E=78°
L=120° or 55°
Maybe this is right, sorry it took so long.
