A section of cuboid wood is 1.2 meters long. If you want to cut it short by 2 cm, its volume will be reduced by 40 cubic cm
1.2 m = 120 cm, 40 △ 2 × 120 = 20 × 120 = 2400 (cubic cm); a: the original volume of this section of wood is 2400 cubic cm
A piece of rectangular wood with a length of 24cm, a width of 16cm and a height of 10cm is cut into the largest cube. How many cubic centimeters is the volume of the cut part
24x16x10-10x10x10 = 2840 CC
The cross section of a cuboid wood is a square with a side length of 10cm. Cut a section of 10cm from the cuboid wood and cut it into the largest cylinder to calculate its volume
3.14×5×5×10
