A piece of wood is 2.5 meters long and its cross section is a square with a side length of 10 cm. What is the volume of 40 pieces of wood? How many cubic decimeters? How many cubic meters?

A piece of wood is 2.5 meters long and its cross section is a square with a side length of 10 cm. What is the volume of 40 pieces of wood? How many cubic decimeters? How many cubic meters?


2.5 m = 25 decimeters, 10 cm = 1 decimeter
So the volume of 40 logs is 25 * 1 * 1 * 40 = 1000 cubic decimeters
It's one cubic meter



A piece of wood is 2.5m long and its cross section is an 8dm long square. What is the volume of 60 pieces of wood? How many cubic decimeters? How many cubic meters?


2.5m=25dm
The volume of 60 pieces of such wood is 8x8x25x60 = 96000 cubic meters, decimeter = 96 cubic meters
So the volume of 60 such logs is 96000 cubic decimeters, 96 cubic meters
