Answer:
860.9 m³
Step-by-step explanation:
We can obtain the volume of the composite figure by subtracting the volume of cylinder from the volume of cuboid.
Cuboid or rectangular prism:
l = 10 m
w = 10 m
h = 12 m
[tex]\sf \boxed{\text{ \bf Volume of cuboid = l *w * h}}[/tex]
= 10 * 10 * 12
= 1200 m³
Cylinder:
r = 3 m
h = height of the cuboid = 12 m
[tex]\sf \boxed{\text{\bf Volume of cylinder = $\pi r^2h$}}[/tex]
= 3.14 * 3 * 3 * 12
= 339.1 m³
Volume of composite figure = 1200 - 339.1
= 860.9 m³
