a² + b² = c²
c² = 19² + 34²
c² = 1517
c = √1517
c = 38.95 units.

Answer: Missing length = 38.95 units ; Missing angles = 29.2° and 60.8°
Suppose the length of each side of the cube is x, so the volume must be:
x^3.
If the volume is 15 cm^3, so the length must be cuberoot(15) which is not integer,. So, the volume of the cube with integer side never equal with 15 cm^3
I think the answer is B

Answer:
10201
Step-by-step explanation:
=(101)²
=(100+1)²
={100²+2(100)(1)+1²} [(a+b)²=a²+2ab+b²]
=10000+200+1
=10201
