The figure is a solid with the trapezium PQRS as its uniform cross-section. Find its volume
Attached Figure / Diagram
A
120m2
B
576m3
C
816m3
D
1056m3
Verified Correct Answer: C.
Step-by-Step Mathematical Solution
Volume of solid = cross section x H
Since the cross section is a trapezium
= \(\frac{1}{2} (6 + 11) \times 12 \times 8\)
= 6 x 17 x 8 = 816m3
