A cuboid wood, the cross section is a side length of 0.5 meters square. 10 such rectangular wood volume is how many cubic meters?

A cuboid wood, the cross section is a side length of 0.5 meters square. 10 such rectangular wood volume is how many cubic meters?

The volume of 10 such rectangular wood is 0.5 * 0.5 * 0.5 * 10 = 12.5 cubic meters

A 2m long rectangular timber has a cross-sectional area of 16dm2. What is its volume in cubic meters
eleven thousand one hundred and eleven

16dm2=0.16m2
Volume = cross sectional area * length
So v = 0.16 * 2 = 0.32 m3

A cuboid wood, 6 meters long, its cross section is 10 cm long square, its volume is how many cubic meters
A cube stone has an edge length of 8 decimeters. If 1 cubic decimeter stone weighs 2.7 kg, how many kg does this stone weigh?

10 cm = 0.1 M
0.1x0.1x6 = 0.6m3
2.7x8x8x8=1382.4
