Could you check this for me?

OpenStudy (anonymous):

A wedding cake is prepared using 3 individual cakes. The first is a rectangular prism with a length thirteen inches, a width 9 inches, and a height 2 inches. The second is a cylinder with a diameter 6 inches and a height 3 inches. The third is a cube with side length 4 inches. What is the approximate total volume of the cake? Use three point one four for pi. Round to the nearest whole number.

i got 448.72 as the volume of the whole cake, i dont think this is right though.. could you check it?

OpenStudy (dumbcow):

i get 382.82

OpenStudy (anonymous):

Okay i did something wrong, let me redo the question..

OpenStudy (anonymous):

you would find the volume for each section then add them together correct?

OpenStudy (dumbcow):

yeah prism -> 13*2*9 = 234 cylinder -> 9pi*3 = 27pi cube -> 4*4*4 = 64

OpenStudy (anonymous):

okay, i dont know how much i got 150.72 on the cylinder...

OpenStudy (anonymous):

I dont know how but* i got 150.72 on the cylinder

OpenStudy (dumbcow):

volume = pi*r^2 *height radius = 3 height = 3

OpenStudy (anonymous):

okay i think i got it, let me redo the cylinder to see if i can do it correct

OpenStudy (anonymous):

now i got 84.78 this time

OpenStudy (dumbcow):

yep

OpenStudy (anonymous):

okay i did it again and i got 28.26 and you would round down to 27, correct?
