A rectangular container measures 4m by 3m by 500cm. The container is completely filled with 0. 5m a long cubic packets. How many such packets are needed to filled 3/4 of the container?

Answer 1

convert 500cm to meters : 500cm = 0.5 m

volume of rectangular container:
v = length x width x height
v = 4 x 3 x 0.5
v = 6m^3

volume of cubic packets:
v = length x width x height
v = 0.5 x 0.5 x 0.5
v = 0.125 m^3

3/4 of rectangular container: 3/4 x 6 = 4.5 m^3
so 4.5 m^3 is 3/4 of the container

4.5 / 0.125 = 36 containers

therefore 36 containers fit in 3/4 of the container

Answer 2

I can't understand where 36 is coming from
