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 section of cuboid wood is 1.2 meters long. If it is sawn 2 decimeters short, its volume will be reduced by 48 cubic decimeters
V = 1200 * (48 / 2)
=1200 * 24
=28800 DM³
What is the area of 2 meters long, 3 meters wide, 4 meters high? How many cubic meters is it?
Surface area = 2x3x2 + 2x4x2 + 3x4x2 = 52 volume = 2x3x4 = 24
