A cuboid wood is 1.2m long. If it is sawed off 2cm, its volume will be reduced by 40 cubic centimeters. How much cubic centimeters is that of the original wood? My mother bought a turtle and put it in a rectangular glass fish tank of 5DM in length and 4dm in width. After the turtle sank into the water, it was observed that the water surface rose by 1dm. Do you know the volume of the turtle?

Do you know the volume of the turtle?

The ground area is 40 △ 2 = 201.2m = 120cm
Original volume: 1.2x100x20 = 2400 cm3
Turtle volume = water rising volume
5x4x1 = 9 cubic decimeter

A section of cuboid wood is one meter long. If it is sawn two centimeters short, its volume will be reduced by 20 cubic centimeters. What is the original volume of this section of wood?

Bottom area = 20 / 2 = 10 square centimeter
Volume = 100 * 10 = 1000 CC

A cuboid wood is 1.2 meters long. If it is sawed short by 2 cm, its volume will be reduced by 40 cubic cm. This wood
What's the original volume? How many cubic centimeters? How many cubic decimeters?

40 / 2 * (1.2 * 100) = 2400 CC
=2.4 cubic decimeter
The original volume was 2400 cubic centimeters, or 2.4 cubic decimeters
