Question

How would I find the volume of the composite space figure?

Answer 1

Impossible to tell with the given information. Do we KNOW that the rounded top is a semi-circle or does it just look like it?

Answer 2

I believe that we know it is a semi-circle. @tkhunny

Answer 3

The box is H*L*W

Assuming the "lid" is semicircular (read: semicylindrical), the volume would be (pi*r^2*H)/2

Answer 4

You need the cross-sectional area multiplied by the length. What is the area of that face that is looking at us?

Rectangular Piece: ??
Semi-Circular Piece: ??
