Question

How many cubes of 25cm side can be cut from a wooden log of 3m length 50cm breadth and 25cm height

Answer 1

Length of a cube: 25cm

Change the 3m length to cm.

3m = 3m × 100 = 300cm

Calculate the volume of the wooden log with the formula Volume = Length × Breadth × Height.

300cm × 50cm × 25cm = 375000cm³

Calculate the volume of a cube.

25cm × 25cm × 25cm = 15625cm³

Now, divide the volume of the wooden log by the volume of one cube.

375000cm³ ÷ 15625cm³ = 24 cubes

Hence, 24 cubes can be cut from the wooden log.
