A rectangular container measures 4m by 3 m by 500 cm. The container is completely filled with 0.5 m long cubic packets. How many such packets are needed to fill 3/4 the container?

Answer 1

V = (3/4) * 4 * 3 * (1/2) = 4.5 m^3
v = .5^3 = .125 m^3
4.5 / .125 = ?

Answer 2

If you express the container's dimensions in terms of packets, it is
8x6x1 = 48
3/4 of 48 = 36
