A truck driver wants to load as many identical cylindrical canisters of olive oil as can fit into the 3-meter × 4-meter × 9-meter storage space of his truck. How many canisters can he load into the truck?
(1) Each canister has a volume of 62, 500π cubic centimeters.
(2) The height of each canister is four times the radius.
Question : many canisters can he load into the truck?Note: To find the number of cannisters we require
1) Dimensions of Cylinder i.e. Radius and Height of cylindrical canister
2) Dimensions of TruckStatement 1: Each canister has a volume of 62, 500π cubic centimetersDimensions of cylinder are unknown hence
NOT SUFFICIENT
Statement 2: The height of each canister is four times the radiusRatio between dimensions of cylinder is given but Dimensions of cylinder in actual are unknown hence
NOT SUFFICIENT
Combining the two statementsh = 4r
Volume = π*r^2*h = π*r^2*(4r) = 62, 500π
this gives us radius and also the height
Now we can divide each dimension of base of truck with radius of cylinder to find the number of cylinders than can be rest on base of truck.SUFFICIENT
Answer: Option C
HI, I have a doubt here.
Using both statements, we get r=25cm and h=100cm. And the dimensions of the truck are 300cm*400cm*900cm.
So wont the number of cylinders differ if we consider 300cm*400cm as the base and 900cm as the height OR 300cm*900cm as the base and 400cm as the height OR 400cm*900cm as the base and 300cm as the height?
