Volume of the bigger container = 8 x 4 x 5 = 8 x 20 =160 cubic centimetres.
Volume of the identical containers = 5x4x2= 40 cubic cm.
The amount of water left in the bigger container = 160- 2(40) = 160- 80= 80 cubic centimeters.
If either of these values ( 8x4x5 or 5x4x2) is height, then it is
=8- 2x5= 8-10= -2 cm which isn't possible
=4-2x4= 4-8=-4 which isn't possible
= 5-2x2=5-4=1 cm which IS possible ..
Therefore the height is 1 cm

Answer:
2.5cm or 4cm
Step-by-step explanation:
(8cm×4cm×5cm) - 2(5cm×4cm×2cm)
=160cm³ - 80cm³
=80cm³÷32cm² / 80cm³÷20cm²(seriously i don't know what is the height of the bigger rectangular container because you didn't specify the dimensions)
=2.5cm / 4cm
