With 50 pieces of the same square wood, pile up a cuboid 2 cm long, 1.5m wide and 1.2m high. What is the average volume of each square wood? How many cubic decimeters?

With 50 pieces of the same square wood, pile up a cuboid 2 cm long, 1.5m wide and 1.2m high. What is the average volume of each square wood? How many cubic decimeters?

2x1.5x1.2÷50
=3.6÷50
=0.072 (M3)
=72 (cubic decimeter)

A cuboid of 4 m in length, 2 m in width and 1.5 m in height is made up of 240 square timbers. What is the average volume of each square timber?

1000 * 4 × 2 × 1.5/240 = 50 cubic decimeter

With 80 pieces of the same square wood, pile into a 2-meter-long, 1.5-meter-wide, 2-meter cuboid. What is the volume of this cuboid
In five minutes

The volume of the stacked cuboid is 2 * 1.5 * 1.2 = 3.6 cubic meters
The volume of each square wood is 3.6/80 = 0.045 cubic meters = 45 cubic decimeters
