The figure is a solid with the trapezium PQRS as its uniform cross-section. Find its volume
-
A.
120m2 -
B.
576m3 -
C.
816m3 -
D.
1056m3
Correct Answer: Option C
Explanation
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
