Answer 1

860.9 m³

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

`\sf \boxed{\text{ \bf Volume of cuboid = l *w * h}}`

= 10 * 10 * 12

= 1200 m³

Cylinder:

r = 3 m

h = height of the cuboid = 12 m

`\sf \boxed{\text{\bf Volume of cylinder = $\pi r^2h$}}`

= 3.14 * 3 * 3 * 12

= 339.1 m³

Volume of composite figure = 1200 - 339.1

= 860.9 m³
