A cube with an edge of 0.04 m was cut out of a wooden block, which is 8 cm long

A cube with an edge of 0.04 m was cut out of a wooden block, which is 8 cm long, 0.6 dm wide and 4 cm high. What is the volume of the remaining part of the bar?

Let’s translate all the values in the problem in cm: 0.6 dm = 6 cm, 0.04 m = 4 cm.
Find the volume of the original wooden block V = 8 cm * 6 cm * 4 cm = 192 cm ^ 3.
Find the volume of a cube with an edge of 4 cm V = 4 cm * 4 cm * 4 cm = 64 cm ^ 3.
Let’s find what the volume of the remaining part of the bar is equal to V = 192 cm ^ 3 – 64 cm ^ 3 = 128 cm ^ 3.
Answer: 128 cm ^ 3.
