(12 points) what is the volume of this shape?

Your answer would be 180 cm³.

We can treat this solid like a prism and therefore find the area of the cross-section and multiply it by the depth.

To do this we can split up the cross-section into 3 rectangles with dimensions 5 x 4, so we get (5 × 4) × 3 = 20 × 3 = 60 cm².

Then we multiply the cross-section by 3, which gives us 60 × 3 = 180 cm³.

I hope this helps!

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9
