Riya made a container using metal sheets such that the container is in the shape of cuboid surmounted by a half cylinder. If the base of the container is of dimensions 30 cm × 14 cm, and the height of the cuboidal portion is 16 cm. She used this container to keep small boxes of volume 210 cm³ each.

Based on the above information, answer the following questions:
(a) How much total area of the sheet is used by her to make the container?
(b) How much air can be hold by the container?
(c) How many small boxes can store inside the container?

It depends on whether the length of the cylinder is 30 or 14

(a) 2(30+14)*16 + π*30*7 = 1408 + 210π
(b) depends on whether the diameter of the cylinder is 30 or 14
If it is 30, then
v = 30*14*16 + π*15^2*14
otherwise,
v = 30*14*16 + π*7^2*30
(c) divide the volume by 210
or, you will have to see how many whole boxes can fit.
and since you don't give the actual dimensions of the boxes, that will entail some work.

Dontcha hate it when the questions are poorly constructed?
