Question

Please anyone solve this problem

Answer 1

3,822.08 cm2

Explanation:

You would start off by finding the volume of the who post which is 4,224. You then would find the volume of the hole cut out which is 401.92. Then you would subtract 401.92 from 4,224 giving you 3,822.08.

Hope this helps!

Answer 2

3821.9 [cm³].

Explanation:

1) the required volume can be calculated as:

V=V(prism)-V(cylinder);

2) V(prism)=32*12*11=4224 [cm³];

3) V(cylinder)=π*r²*32=3.1415*4*32≈402.1 [cm³];

4) finally, V=4224-402.1=3821.9 [cm³].
