Sup guys so today in math class Mr.Backe asked us if we did Check Your Understanding on page 31. No one did it so we did the problem together. First Mr.Backe drew the cake like this one:

So Mr.Backe told us to draw the top view. Then he asked me what happens to the circle on top. So I said that it blends in with the square part of the cake.

Then we had to draw the side view which is the one you see in the bottom picture:

So the reason why I have 20 cm d is because to find the circumference you need Pie D(diameter)

so to get the surface area Mr.Backe wrote the answer down so here it is:

= 625 + 314.2 + 500

= 1439.2 cm²
