Have half done, need help with other half.
A company manufactures aluminum mailboxes in the shape of a box with a halfcylinder top. The company will make 1173 mailboxes this week. If each mailbox has dimensions as shown in the figure below, how many square meters of aluminum will be needed to make these mailboxes? In your calculations, use the value 3.14 for π , and round up your answer to the next square meter.

Best ResponseYou've already chosen the best response.1my question is whether the semicircular to is closed or open..? you need the surface area of the mailbox front and back rectangle A = 2 x 0.23 x 0.35 = left and right rectangle A = 2 x 0.55 x 0.35 = rectangular base A = 0.23 x 0 55 = so find those areas now the curved top. closed cylinder = radius is 0.115 find the \[ A = \frac{1}{2} \times( 2 \times 3.14 \times 0.115^2 + 2 \times 3.14 \times 0.115\times 0.55)\] if the cylindrical top is open... delete \[2 \times 3.14 \times 0.115^2\] from the calculation. when you get the surface area of 1 mail box, multiply by 173 and then round the answer up... to the nearest square metre

Best ResponseYou've already chosen the best response.1I haven't done the calculation, I just explained how you should go about finding the surface area of 1 box then finding the total area of metal needed.
