What is the volume of the composite figure?
2 answers:
For this case we must find the volume of the figure composed of a parallelepiped and a pyramid. The volume of the parallelepiped is given by:
Where a, b and c are the sides
For its part, the volume of the pyramid is given by:
Where:
Thus, the total volume is given by the sum of the volumes.

Answer:
The correct option is option (c).
Step-by-step explanation:
Right angled triangle:
- One angle must be 90° and other two angles are acute angle.
- The hypotenuses is the longest side of the triangle and opposite right angle.
- It follows the Pythagorean Theorem.
Given that,
∠QRP= 90°, ∠RPQ= 30°, ∠PQR = 60°
we know that,
for sin P , the opposite is QR.
The hypotenuse is PQ.
Therefore,
